Thanks for the feedback @Gerry and welcome to the community 
About preferring to host only a certain gender, we had quite some discussions about it in "Preferred gender" option for hosting.
In my understanding it’s left to users for now to spell out their preference because we didn’t find a checkbox solution that simply works across the board. It will more likely require some fine-tuning and iterations that are not on top of the roadmap right now. But if you have more ideas to share on this, please join in on the linked discussion!
Improvements to the interface like hiding empty fields and adding at least a home pic are certainly on the list of the UX team.
About adding more filters and checkboxes, I think @Aleja shared an interesting perspective on this in Do we really need so many checkboxes and filters?. At least me, I’m also strongly in the less-boxes-more-conversation camp
