I would stay away from user serviceable or modular cans.
If not taken apart every 40-50 rounds the threads carbon seize even with oil or anti seize. This happened with 2 of mine. They are not as strong as full welded cans and have longer min barrel length restrictions, which is an issue for me but won't be for everyone.
A direct thread can seems easiest and cheapest for bolt rifles. CB or Xeno mounts have more surface area and seem to lock up better with less torque but you also have to have a mount for ever rifle if don't want to move it over constantly.
Key mod, xeno, CB, and locking mounts are nice for ars. The cb has a replaceable o ring that keeps carbon from reaching the threads.
Ti cans are nice and light for hunting. Steel may be better for full auto and long strings.
Full welded Ti cans can be cleaned with clr.
Stainless the most effective method is probably the dip but it's toxic.
Aluminum cans such as some rimfire can't be cleaned with either.
That's while Il just stick with full welded ti cans from now on for bolt rifles.
I have never had an issue with carbon pieces or burnt powder kernels in the bore although I do find them occasionally in the action/barrel. After I shoot I just hold the rifle muzzle down a sec so if there is any in there it falls out.
My favorite hunting can right now is a gen 1 TBAC ultra 5.
My next can will be a TBAC dominus or a Dead air Nomad Ti.
My buddy just picked up a nomad 30 so Il be trying it when it arrives.
To the op my buddy has a sandman S they are nice my friend has no complaints and neither did I when using it. I was like you at first and wanted a user serviceable can but I wouldn't go that route now. If I could only have one it would be the nomad Ti or the dominus. I think they will be the best compromise of suppression, weight, and length for a bolt rifle set up for hunting.
Or just give in like the rest of us and get several cans.
