What is the planned cabinet overhang? 1"? 1½"?

1.5" but I am not sure what is best.

Are you interested in layout feedback at this stage?

ummm, prob not, lol. Cabinets are ordered.

I got 60 square feet, without a back splash. And 33 linear feet for edging. Too many unknowns in the mix to be accurate though. Like edge type. 2 cm vs. 3 cm stone and the consequences that has on both edging and square footage. Whether or not whole slab purchases are required vs just the amount of stone needed. The stone itself and it's pattern and if more stone is needed for matching that pattern.

Stone doesn't use 45 degree mitered cuts. 90 straight across seams only. Miters are only used by hacks using blanks.

Thank you for the clearance tip! I wanted mitered edges, to look like 2", but the stone is 3cm. I do not believe there is a miter on the seeams though, When we discussed it is sounded like were straight. Do you have advice on where the seams should be? Or where I should ask them to be I guess?

I wasn't considering the laminated edges, but the straight seams should take less material. (Not considering the pattern.) I'd ask them if they can make the peninsula and right counter L one piece without a seam, and make the left counter and short L without a seam also. They'll have to put seams in the sink area.

That plan looks as if it might have been drawn for laminate tops and a drop in sink, hence the mitered corner. What kind of sink are you planning?

The plans were not made by the counter company. The counter guy suggested a seam in the sink area, but I was not sure if that was standard or not. But I want a silgranit undermount.

If you'd like to research seams at sinks, there are quite a few GW threads that address the issue:
