>>156796try Danbooru with the rating:safe tag and Safebooru which is entirely sfw, also Furbooru which still has porn but way less of it in comparasion to other sites (again, there are filters that can help you)
one thing you can also do is find a furry artist on Twitter and look at who they follow, you can usually find more artists there
you can never be 100% safe since something considered sfw may still be off-puting (like overly muscular characters for me) so tags (and blacklisting them) are your best friend when it comes to boorus
