Concierge Class perks? Worth it for someone with mobility issues?

So my husband 47m had a medical situation a year and a half ago and can’t walk super long distances or get around as well as he did before while he is healing— he uses a cane in public right now. This is his first cruise (I’ve cruised before) and I’m really trying to make it a good experience for him.

I booked a concierge class balcony in hopes that the priority boarding and disembarking will help reduce the potential for him to have to stand long times… I also hope we’ll be able to do the concierge class lunch the first day so that he isn’t inundated by the buffet craziness as his first experience. I also was able to pick a room not too far from the elevators for us.

Anyway— can anyone vouch for concierge class being worth it for our needs? Or if there are any other particular aspects of it you enjoyed, I’d love to hear. I’m stuck with it now I guess but I’m hoping it wasn’t just a price jump with no real value.
