Lawnchair best

Vivaldi is the best alternative for someone who wants Chromium, at least on Android it complies, except for its adblocker, it is basic compared to UBlock, in that case I would go for Librewolf and IronFox on Android

Keepass is good, with Synching you can synchronize everything better

Maybe RethinkDNS

Or even DNSNet if good lists are added to it

Better use Seanime, it is more complete and has a web interface, it is even in the Termux repo
