Within f-droid, though they're also on google store I assume, I can recommend Simple Mobile Tools. Just one Slovakian dev but the apps can replace various stock and non-stock apps and work fantastic. The names are a bit generic though, like Simple Gallery or Simple File Manager.

They're powerful enough for me, and simple enough that I install them for my mom and grandma (grandpa can't read, dad chose the dark side), and my brother apparently also discovered them independently. Few months ago I figured I should take stock of how many of these apps we use together and did a donation for us collectively. One benefit for family members is that now they don't have to get used to a new interface if they get a new phone, so they're less locked into one brand. Android UI always changes and just gets worse imo, and unfortunately you need the stock camera for good quality pictures, but at least things like their gallery always looks the same.

Yeah they're on the Google Play Store too:

I use half of them and agree completely on the peace of mind they bring when changing phones or onboarding other people.
