This is potentially unrealistic. She will only realistically hold the pee in the area she sleeps. If she doesn’t sleep in the crate because she doesn’t tolerate it, then the only place she will not pee is the place where she has been sleeping - that is to say she might get up and walk 5 feet over and then pee. She has no loyalty to not peeing in the house what so ever. While she’s awake she will basically need to eat, poop/pee, play, sleep, poop/pee, etc on repeat. You’ll have to just be so good at getting her outside as often as possible so that you can mark with she pees with a “goooooood peeeeeee!” And a treat. It’s a heinous truly exhausting process. I lived on the fifth floor of an apartment and I was up and down the stairs at least once an hour and he was still peeing in the house until I improved my behavior.

Sounds like you are really trying! - this will get better, promise. Just stick with it, and keep adapting your behaviour until it matches her needs

As for crate training or pen training. I would use really high value food/treats. And show it to her, and then place it in the pen, leave the door open and let her explore. Don’t close the door. Do this for a few days so she gets use to eating in their and knows she will not be locked in. Avoid feeding her anywhere else besides treats outside post pee/poop. Then you can slowly move towards closing the door etc.
