I think you've got most of the pros and cons.
I have a bunch, and tend to use the big mouth bubbler, plastic. Easy to clean, and I like to watch. I don't sweat the lid not sealing well.
The only thing I might point out is the siphonless option makes me nervous. That spigot has a lot of parts and nooks and crannies that can harbor infection if you don't disassemble and clean it thoroughly. I'm probably overreacting to it, if I'm being honest, but I am always wary of things that are hard to clean.
Speaking of hard to clean, I'll say the plastic small mouth carboys are my least favorite, and I only ever use them as a secondary. A crusty krausen ring would be a nightmare to get off. Yes, you can soak for a while, but not being able to get in there to scrub at it would drive me nuts.
