I feel a bit like you've all been here before and knew not to answer,
Not me, I just had enough sense not to tread in areas I do not know - my expertise lies in multi-multi-multi-booting Linux (usually run over 60 of the suckers), and Timeshift.
It's great, though, that you have nutted a lot of it out for yourself, that bodes well for your Linux journey.
and have learnt a sh*t load in the process!
Plenty more where that came from, but we feel it is well worth the effort.
Enjoy your Linux, and stay safe from COVID.
