So I found out that this is mainly a problem of body height. With my 1.65 m I can only reach the lowest compartment of an upper cabinet with a normally deep countertop, my husband (1.92 m) has no problem with a deeper countertop and the highest cabinet compartment.
I think you have to take it into account depending on the height of the users as well. 10 cm more is not a problem though, I don’t notice a difference. But then the base cabinets are also on feet/foundation and no longer hang on the wall at the back. They are generally 60 cm deep anyway.
Instead of an oven, you could also use a combination oven, which is often smaller and also has a microwave inside. I just find that more realistic for single young people ( :D ), they are more likely to make themselves a pizza or warm something up in the microwave than to need the giant oven for the turkey.
