There are many granites that do not need sealant because they are very dense. I have never sealed my granite counters in 3 different kitchens in an 18-year period. I always chose granites that do not need sealing. You could also look at soapstone which does not need sealing. You don't even have to oil soapstone if you don't want to; many people love the natural more pale look of unoiled soapstone.

I personally would not be a slave to my counters, to be always worried about them, always worried about people spilling or leaving glasses on the counter, and having to re-apply walnut oil or whatever (you will have to clear your counters for that each time). But that is my personality, you may feel differently and like the marble more.

I have soapstone and I do like to wax it occasionally. I started with the one our fabricators gave us. It has a strong, but pleasant fragrance because there is rosemary oil in it. I changed to a less expensive, but similar product by Howards. It is mainly just carnauba and beeswaxes. It’s applied thinly and then wiped with dry cloth until it’s no longer oily to the touch. I’m not concerned about toxicity at all. https://www.howardproducts.com/product/wax-it-all/

I have one of those dense granites that doesn't need sealing. In fact, I'd had it for about ten years before I found out about stone sealers. When I got it, I thought it would be great to roll out dough on, and I wouldn't have to get out the heavy pastry marble. However, I did that exactly once. Counters are too high for me to comfortably roll out dough, and I find the idea of kneading on them absolutely inconceivable. So the pastry marble still comes out and gets placed on the kitchen table

You are obviously not a natural stone person. Buy laminate instead. No dnake oil hokum BS involved with it.

Thank you for the comments. I didn't realize until just now that anyone commented. Mad_gallica, you are so right. Average height people can't roll or knead on a 36" high counter, and I am 4'10'! I love soapstone for its ease of caring for, but we ended up going with a Fantasy Macaubus Quartzite. The space is basically gutted now and nothing is installed yet except for floor tiles which had to be ripped out.
