The OSS solutions include: Jitsi, Bigbluebutton (BBB) and Galène. I toyed with Jitsi when the pandemic hit but was battered into using Teams instead. It was very quick in my estimation. Teams and Zoom suffer from (hyper)scaling issues. They have way more resources than you and I but when lots of people decide to use it simultaneously then it will suffer - death by a thousand or millions of cuts. If you can self host on a reasonable platform then you will almost certainly get a far better experience than any big jobbie. You will need suitable internets for your server too. You will want 10-30ms latency and roughly 5Mbs-1 per attendee for 1080p. So for 25 users, you will need something like 150Mbs-1. For you, I would get your mates together and self-host. Surely you have a nerd who could run the thing for you? If not, then farm it out but do be careful. Obviously, where you actually are is rather important. I'm in the UK and will have rather different advice for a substantially different environment.
