Make sure the cell provider hasn’t banned the model. AT&T banned a bunch of perfectly good unlockable international phones and kept the locked local ones not supporting lineage. They still work of course, just can’t make calls.

There’s a ton of junk - Bixby, the Samsung cloud apps, I have one I have to keep stock for work and another i have Lineage on and the difference is very noticeable, battery drain for one

If you have to ask, the answer is yes
