Regarding military service today, bear in mind
that Christians are prohibited from deliberately killing others. This rules out
serving in a modern-day military, since being trained and used to kill others
is a key part of the role. In contrast, roles like riot control, investigating
crimes such as theft, murder, and other civilian duties do not require the need
to kill, so a role in a civilian police force or civil/home guard is
potentially more acceptable.
In
Bible times, all these civilian duties were also performed by elements of the
military as there was no such thing as a formal civilian police force, so at
that time there would have been no distinction. So with regard to someone like
Cornelius, once converted to Christianity, he could have transferred to (or
perhaps was already serving in) a more 'civil' capacity as a guard or
administrator/trainer/etc, but still retain his rank and position in the Roman
military.
So
today, I would draw the distinction between serving in the military (where a
willingness to kill is essential) and serving in a civil guard or police role
(where it is not), in terms of your likely exposure to behaviour that could
violate Christian standards.

I agree with your opinion. If I just look a little at the area of soldiering and how the NT refers to it, I observe that the NT-text approach is very ambivalent: John the Baptist tells (Luke 3:14) soldiers that they are not to abuse anyone. There is nothing there about them necessarily having to end their military career. According to Matt 8:10, Jesus values the faith of the officer.
But the soldiers of Herod (Lk 23:11), as with Pilate (Mt 27:30), mocked or beat Jesus. The case of Cornelius, an active officer, has been described.
Paul is indeed arrested by the officers and soldiers (Acts 21:32), but this saves him - prolongs his life. They respect his Roman citizenship (Acts 22:26) and respond with further increased protection for Paul when they learn that the Jews want to kill Paul (Acts 23:23). Before the shipwreck, the soldiers want to kill Paul, along with the other prisoners. It is again the commanding officer who prevents this and again prolongs Paul's life (Acts 27:43).
From this brief analysis, it seems to me that the NT-text does not in any way invalidate the position of the soldiers. The context shows that the term "soldier" in our day and "soldier" in the NT-period do not exactly overlap. A soldier/officer, in addition to being part of the military structure of the Roman army, often acts in the role of a modern-day policeman or prison officer...
On the other hand, it is also true that the little boys in Bethlehem, were murdered directly by Herod's soldiers/police (although this is not directly in the text) or it can be assumed that they assisted in such an action, which was probably some sort of a cover-up to separate the parents from the little children... The soldiers/police who were supposed to guard the tomb, were put in a very precarious situation when they left their posts out of fear (Mt 28:4). They had to be bribed to testify that the body had been stolen, and in case of further inconvenience, they were given a promise that it would not affect their military career (Matt. 28:11-15).
A difficult question arises: Can a Christian be a soldier? Or a policeman? Or a prison guard?
I answer it this way:
I do not decide whether it is wrong or right. This statement is a latent criticism of globally operating churches like the JWs who centrally decide on a one-size-fits-all doctrine, even though it is clear that the military, police, or prison ministries in different countries are different. Is military submarine service permissible (see Jonah 😊 )? But what about states that don't have submarines?
If centrally led churches decide what is or is not permissible, or globally prohibit/permit it and don't respect regional specifics, then the result is similar to JWs with the issue of blood, blood fractions and platelets, autotransfusion, etc. etc. ... an absurd ban with even more absurd exceptions...
So I am not saying whether it is wrong or right, and which kinds of troops or services are or are not allowed, but rather I am focusing on the answer: if one is a soldier or a police officer and wants to be a Christian, one must be aware of the increased risk of being in a counter-ethical situation with one's own conscience. He may serve his entire service on a military submarine as a cook, opening cans and cooking delicious meals out of them 😊, he probably won't do anything more sinful than working as a taxi driver or a shop assistant or a school teacher, but the situation can change quickly...
But he can encounter counter-ethical issues just like a doctor (abortion, sex change...) or any other profession. Not something more or less sinful per se, but there are professions that are simply more risky than the other. And that is for each person to judge in their own time, in their own region, in their own conscience, and in their own relationship with God... global, there is no one answer in my opinion. That's my global answer 😊.
