What kind of bed to get?

My daughter is coming up on 2.5, and she’s still comfy in the crib, but I can tell it’s time to transition to a bigger bed (plus I’m pregnant and we’re gonna use the crib for the baby later this year). I really have no idea where to start though.

I was looking at floor beds, but will she developmentally outgrow that soon? I know many younger toddlers use those, so should I get her something more “big kid” to last her longer? Any advice, photos, and links welcome!
