Authelia should come with rate limiting to protect against brute-force attacks. That could be enough.
I'd generally advise to make sure such protection actually works. Like look up the limits and try to login with a wrong password 30 times... Especially if you added stuff on top (fail2ban, crowdsec...). Has happened to me I misconfigured stuff and it didn't limit anything... Now I check to make sure for important bits like an authentication service.
Do make sure that you can eventually get back in after testing, though. Sure, it's safer when even you can't access it, but... :p
i do have ratelimiting configured but yes i never tested it which i should
Guess if it works, you don't really need fail2ban as f2b pretty much does the same job. I mean it can do more, but you don't really need to protect against PHP issues, broken wordpress plugins etc since none of that is part of Authelia.
I use fail2ban, as I have SSH running and several other services exposed which come with default fail2ban configurations. And I never got crowdsec running properly. So I skipped it. I think frequent updates and all those things are more important than a web application firewall anyway.
