Not OP, i've heard nothing but good things about cloudflare tunnels but for me they have two major drawbacks. The first is you can't use them for a self hosted media server such as jellyfin as it violates their terms of service. The second is you have to trust them with all your traffic. Now i have no reason to think they would do anything nefarious but i'm at the point in my threat model journey that the less i trust in any corporations hands the better. Just my two cents.
