All of your suggestions are great - I have built my own and bought some nasty to put together 2 man ladder stands, then hang on stands - but seems like I get the stand set based on scouting for October bow hunting and then the deer pattern changes after the rut when food and bedding dominate. So, take down the stand and move it - as my land is inaccessible to ATV - that means take it apart - move (a couple trips) - then reassemble and attach - pretty full day there and I too am not getting younger. I was thinking about a climber stand but I really don't trust that too much.
I have used a seat that attaches to tree and you keep your feet on the ground but that limits your view more than being up high - same with the ground blinds, only use those when I need to stay out of wind / cold - add in that ground level bowhunting is extremely challenging - you need lots of cover to avoid being spotted

I have a hang-on with adapters so that I put the adapters in several trees and just move the hang on stand, but that means putting in several sets of sticks or moving sticks and moving hang on - while the adapters make the setup and attachment easier, it is still a process.
