There are any number of architectural elements that can be added, however, without a picture. it's little more than a conversation perpetuator.

sigh

You're right. I'll have to break down and take a picture.

I'll update with one shortly.

pictures of counter (albeit, a sideways picture. Sorry.)

To decipher what you are looking at, that is the countertop on the left. You can see how large the overhang is.

No knobs or pulls on the vanity yet. Not sure what to do with it.

Sorry to make you turn your head sideways. Not sure how to spin the picture.

Still sideways, but you can see more counter.

Add a 2-1/2" crown along the top rail an "G" or "H" molding on each end vertically with plinth blocks.

You can always pull your cabinets forward the extra distance and put block spacers behind them for support. You may have to do a bit of cut out in the back of the sink cabinet. My kitchen counters are mounted this way so I can have extra deep counter top; instead of the standard 25 inch deep counters I have 33 inch deep. There is a cleat on the back wall to support the back edge of the counter, and spacers between the cleat and cabinet backs and spacers between the back wall and cabinet bases so they can be screwed to the spacers like they would be screwed to the wall normally. The spacers are screwed to the wall studs.

Rip the front edge off and install a piece of solid surface?

It doesn't look that bad in the second photo. I just paid extra to get a 1 1/2" overhang on a countertop so that may be why I don't find yours that offensive. What I hate is when the front edge of the top is even with the drawer & door fronts and every spill drips down the cabinet fronts.
I would add some large handles and see if that balances it out to your liking.

What you should do is to call a granite company to let them cut the overhang and do the edges on the site. It is now a hard process just takes around half an hour and cosrt you $300 may be..

I'd just go around the bottom with a little piece of trim painted to match. Or I might leave it--it's not that bad in the photos! But a very simple piece of crown molding (if you can find it small enough) would work. Simple to go with the cabinet lines...

It looks nice. Don't be upset!
