Using the Jitsi website has worked well enough for me for years, and the calls are P2P as far as I'm aware. What's the advantage of hosting your own? Just preventing jitsi.org from seeing call metadata?
But hey, it's free. And it hits the most important consideration: it could not be easier to use. That's pretty critical since my club mates don't have much capacity for troubleshooting.
(I.e., there is no universe in which Jitsi's possible/likely abuse of this data is remotely close to Zoom's)
With self-hosted, you're simply paying for the servers. If you can pay for the servers and maintain them, you can be confident they'll stay up.
The hosted product is great, it just seems separate and off topic to me.
