What do you mean “no cross device support”? KeePassXC supports Win, Mac, Linux and there are iOS and Android apps available…
As for the lack of cloud and requirement to provide your own synchronization, for some (like me) that’s a feature, not a limitation :)
Do any of the iOS or Android apps support passkeys? I looked into this a couple days ago and didn’t find any that did. (KeePassXC does.)
Keepass2Android doesn’t have it yet, but seems to be working on it

Strongbox seem to have their implementation done for iPhone

I don’t use passkeys so I don’t know. Maybe I should research into passkeys, what’s the benefit over plain old (long, randomly generated) passwords?
Ok, from a quick search, it seems passkeys rely on some trusted entity (your browser, OS, …) to authenticate you, so, yeah, I’m not sure if I like that. The FIDO alliance website is all about how easy, convenient and secure passkeys are, and nothing about how they actually work under the hood, which is another red flag for me.
I’ll stick to old-fashioned, long, secure, randomly generated passwords, thanks.
I’m no expert in this but the passkeys really on some sort of public key, cryptographic pair. Your device will only send your encrypted cryptographic secret when it gets the correct encrypted cryptographic secret from the destination. This makes it much harder to steal credentials with a fake website or other service.
From a quick search, Keepass2Android doesn’t have it, not clear if they’re working on it: https://github.com/PhilippC/keepass2android/issues/2099
KeePassDX similarly has an open issue, not clear when/if it will be implemented: https://github.com/Kunzisoft/KeePassDX/issues/1421
Good to know about Strongbox on iOS, though I’m on android so no bueno for me.
