Just use Firefox, they allow extensions on mobile and you can download Firefox from the regular app store.

I use ad-away. It requires root, but it can block ads in any browser or app.

I think Firefox Focus has ad blocking built-in.

If you are on android 9 you can set a Private DNS that will stop loading of most ads on the whole system.

the one I use is dns.adguard.com

If you use Firefox as your browser app you can install all the same add-ons as the desktop version. uBlock Origin is great.
