Apparently its flight deck can take an F-35B...
I very much doubt the F-35B will ever operate from a cruiser/destroyer pad. It would be VTOL only with no meaningful payload. Party trick only.
that the US Navy currently has only one ship that was designed after 1985 available for operations, with the rest being tied up in port due to serviceability issues. Don't know if that's true.
That is very much untrue. The LCS ships (both designs) have had some problems keeping them in port, but there are many other ships at sea right now just fine thank you.
