Oh, you don't want them flush. When you spill something, it would drip down the cabinet faces. I would say, at least 1".

I didn't appreciate the 2" counter overhangs in my kitchen until the first few significant messes. I'd rather most spills end up on the floor instead of inside every drawer in my base cabinet.

1-1/2” is perfect.

The finish of the edge is more important. No fancy edge. Simple straight slightly eased top edge. No ogee or other sculpted edging.

Like this.

We have 1/4” and are very happy.

Someone had remodeled this kitchen to a scant 1/4" (maybe even 1/8th) and I hate it. To wipe crumbs from a counter, I almost have to open a drawer and insert my hand. Trust me, that is not a guarantee you will get no crumbs at all inside the drawer. A wet spill is even worse. Liquid can go into the lower cabinets or at least down the inside of the drawer faces or doors and there is not only the outside to wipe up, but the inside too. It's a roomy kitchen with plenty of storage, easy to cook in and my friends enjoy cooking here too...but the cleanup is complicated by the lack of any overhang. It's a little thing, but still an annoying little thing.

I agree 1.5 is perfect I have done 1" it is okay I also agree keep the edge profile as simple as possible like eased on the counter and do not do a stacked edge

^ chip factory pictured. Round the top and bottom please.

Especially at sinks.

Do 1.5”. It still will look clean and Scandinavian and be easier to keep clean.

I investigated this as well on my kitchen remodel and learned how extremely practical it is to have an overhang. They are really quite functional and I'm sure you can find some Scandi inspiration pics that have them.
