Without Pro, I cannot choose macOS style interface at all? I think that looks the best.
The macOS style looks very close to out-of-the-box Gnome from what I can tell. There are free themes that will also look like macOS if going for the macOS look is your goal: https://forum.zorin.com/t/making-zorin-os-look-like-macos-bi... Comes down to installing WhiteSur, a few fonts, and an icon pack.
At any rate, as techie, I could make it look like macOS, but I was thinking of installing it on family members' computers without much effort.
