On Android 9 and above, you can also use the Private DNS with a DNS provider that blocks certain domains from resolving, like NextDNS. The advantage is that it doesn't require an additional app, and doesn't require a on-device VPN (which always felt hacky to me, and prevents the use of a real VPN). Possible disadvantage is that I've seen private DNS break connectivity on certain connections like captive portals (though I've now learned if my phone claims to have no internet access when connected to networks, its pretty much always this private DNS thing).
