Both plans appear to be unfinished and not very architect-like. In plan A, there are only 2 windows? Even this is an oversight, it seems like the kitchens would be dark. Neither plan has logical storage? Where do coats go? The vacuum? Bed linens? One plan has WD and DW adjacent— is that dishwasher next to a washer dryer? Weigh whether you prefer the best water views from bedrooms or public/daytime spaces. I think there is room for much improvement overall.

I believe you have another thread on this lake home?

All the versions show a recessed entrance. I'd bring that forward enough to create space for the garage door into the house. The space in the kitchen is more useful as counter.

"I met with an architect today and we came out with two options"

Find a competent architect that takes longer than a day to come up with a more detailed and complete solution that meets your needs and fits your site.

Are these for yourself or are you building them to sell?

I hate to say this, because some of the plans I am going to suggest have issues themselves, but you see a lot of these 1-story narrow plans in FL. For some ideas, look at plans from Del Webb, Anchor Builders, Arthur Rutenberg, Lee Wetherington, M/I Homes. These are all large tract/production builders who have been around for a long time.

Neither one is good

If North is up on the map, then I would probably place the garage flipped than what is shown. And have Living getting more south sun and make sure a massing is not blocking outdoor living to the SW direction.

I like plan A. Kitchen will get south west exposure and living will get north exposure. Indirect light in living room is good. Like that you welcome guests into your sitting space and not a dining room.
