Yandex Browser on Android [which is based on Chrome] supports Chrome extensions. I'm running it with uBlock Origin, Privacy Badger and a few others. If an extension won't load directly from the Chrome Webstore you can toggle 'Developer Mode' under 'chrome://extensions' and load the downloaded and unpacked CRX directly.
I had high hopes for Kiwi Browser but, unfortunately its text-reflow feature has been broken since forever. Yandex Browser is the only one available on Android that ticks both those 'must have' boxes for me: full support for extensions and a functional text-reflow feature --without which a huge swathe of the web is unreadable for me, due to microscopic text sizes.
I know other browsers have their own built-in ad-blockers, but I prefer to use uBlock Origin across all my devices so, when I setup a new one, I can just import my existing rules & settings, built up and tweaked over many years, rather than start from scratch.
