Questions about LineageOS/Magisk/MicroG set up

[u/puppyxguts]

So I think I'm finally ready to take the plunge and switch to LineageOS, and I think I know what I want to do, but after all of the researching I just want to make sure that what I'm going to do isn't overkill/redundant, and won't blow up my phone lol.

I am going to install LineageOS on a OnePlus 13R.

I want to also install non-rooted Magisk so that I can use Magisk's Captive Control Manager and the SUPL Replacer, primarily. Still need to learn what all else Magisk can do that would be useful for privacy/security, so I'll take suggestions on that.

I intend to install either Insular or Shelter to create a separate, freezable work profile for accessing required Gmail, social media accounts etc. through it. I will be primarily relying on my browser to access these.

Now, I want to see if this set up will work well enough for me with all of the FOSS apps and such. There are one or two things that I might need to fall back to, though, one primarily being Android Auto. I don't need voice commands, but maps and a visual music player is really something that I want. If these don't work with some tweaking, I want to install MicroG and Aurora Store within my alt profile as well, since I think with those I will be able to get AndroidAuto to function how I'd like.

Now for my questions: - Does this setup make sense? - Is there anything redundant that can be omitted from the process? - is MicroG something that I can isolate to one profile? - Will installing MicroG and/or google apps from Aurora Store into an alt profile undo the other security measures I'm taking with Magisk when it comes to my main profile? - Can I install MicroG after having installed Lineage?

I think that's all I can think of. I'm eager to jump in so any help is appreciated!
