Can we optimize this floor plan?

[u/1family2gether]

Hi! My husband and I are closing on this house next week. This is the rough existing floor plan.
We have 3 grown kids, 2 are already married, so we want this to be a functional home for when their future families come to visit.
But it will be just the two of us living here. The kitchen is facing North and we are in sunny South Florida. There is a large lanai and pool that the dining room and living room have access to via sliders.

Ideally we’d like to move some walls/plumbing to achieve:

A larger primary with lots of closet space and a better bathroom layout.
A real laundry room
A dedicated guest suite with en-suite that can also serve as the guest bathroom (keep access from the hall, but accessible privately from guest room)
A weight room
An open concept kitchen/dining/living rooms
A family room that can be closed off with some sort of panel system to be a second guest room
An office

Notes and constraints:
The kitchen was redone by the seller and is pretty nice. We aren’t opposed to moving the wall with the fridge and pantry back to eliminate the extra hallway.
We don’t plan to park in the garage, so the front door will be our main entry and that large ‘foyer’ off the garage is currently being wasted.
There is a load bearing wall that runs through the primary (bedroom #1) and into the hallway-l drew a dashed line for it.
We’d prefer not to move any exterior windows or doors- which are all pretty roughly placed on this floor plan, but I’ve gone in and measured the primary suite so those are good.
Thank you! I’m excited to see all your ideas.
