Good questions, the toilet thing is probably more what YOU mind than us. I don't think the majority of us here are adverse to natural facilities. But obviously that will mean peoples leavings on your land. Perhaps give the option by having a portaloo on site. Even a long drop or composting system.
As for woods personally I'm a woodland fan, but here you've got everything from hill dwellers to field fans to people like me. Ideally a mix of sites i.e a little field a little woodland. Does fresh water run through your potential site? If not plumbing in may be a good idea.
As for firewood will the woodland be coppiced and managed? I'm sure 99% of members here wouldn't like the idea of damaging the wood, I certainly wouldn't.
Perhaps a kind of split system a little like brockwell where there are separate pitches aimed at tent, hammock, tarp and bivvy users. Are you adverse to the building of semi permanent natural shelters or possibly even permanent ones left for people to use? There's a lot to consider
