Row, being an Old guy (64 next month) I’m more inclined to go for the most stable platform possible ...

too old for stand up paddling for a distance ... Wide, sit on an ice chest, would be better suited for me (fishing).. My thoughts for purpose are those
Quiet lakes, streams , something to drag along on top the Foamie trailer

Around here shallow bayous and marsh areas provide a goodly amount of large Tasty Fish .. if you can get to them .. <12’ water... Don’t have to paddle far ..

Been fishing in shallow marshes since I was a kid (some time ago) , 16’ flat boat , had to keep an eye on the tide so we didn’t get stuck back there ... and then there’s the Gators

( Like Bears up North

)
For these young -un’s and just sporting around , they want 32” wide X 12’ long,, which should be very stable ... for them ... and then they don’t mind the swimming bit either..
Just from all the reading , seems like different boards do different things ... as far as paddling , stability and either flat or wave use ... I guess if you’re really Into it , you’d have several different boards, depending on varied usage ..
Could get Pricy !!!

And then you need all those “accessories” too ...
