Mock up 45 in of cabs...give yourself 15 in overhang. its cozy but I think its nice and you will get seating use it appears. 24 in deep cabs....for the cabs facing the camera..try 15 in then 30 in stacks drawers or three 15 in wide stacks. I'd take a 30 in wide stack and one 15 in wide stack. These are normal depth so the 18 inches of width across from fridge can have a pull out base pantry...it pulls out toward fridge]...it might end up 15 in with filler strip---still extremely usable...... that uses your 42 inches out from wall. Whats with the doors you show? side hinged cabs???...dont do that....DRAWERS! better storage so you CAN cut back a few inches to give the better knee dimension at overhang. Maybe one large pendant on a dimmer in the middle. Two floating shelves...approx length you show....raise the lower one up a bit and eliminate the top one. Reachable from fridge side is good...my arms are long enough to reach and find those usable....but the third top becomes redundant as its too far....

If you are going to have pendant fixtures I think you have place them in the most logical location. You've kept them away from the shelving. If the peninsula is to be used as a work surface I would install a downlight above it - probably centered on the cabinets instead of the countertop.

I 1000% agree with herb flavor - go drawers - lots of drawers!!

In regards to the pendants, It would be good to see a picture of the whole space to have a better idea of what other lighting is in play. Maybe add some can lights? track lighting? There are lots of options...

Maybe a wall light instead and where does that door go to by the stools I agree a bit more space for stools 42” is onlt going to allow very tiny stools.I would nix the open shelves which will be hard to reach anyway and add a really great piece of art there
