UPDATE*** Help me with figuring out my flooring!!!

WOW!!! Was not expecting my last post to blow up like it did 😂. Seriously thank you all for the comments and input… even the insults lol. I have no idea how to move forward still but need to make a decision soon. I added some more pictures of the space and hopefully it adds the context the first post was missing! We ripped up 30 year old carpet that had animal pee through the subfloor so we are replacing those aswell at the top of the stairs and front floor entrance, along with refinishing the stairs. The kitchen is getting new appliances and we are painting the cabinets. The reason why I was thinking about lvp was to just make the entire floor uniform rather than having a bunch if different kinds of flooring. So my follow up questions are: - What would you suggest I put on the kitchen floor and places i replaced the carpet?
- As some mentioned, this may not actually be hardwood. I added a pic of a corner that fell off and it looks suspicious. Does anyone know if I'd even be able to refinish these floors? - Some areas are not level, what are options to remedy this (mostly in the middle)? - if I were to leave the flooring as is how should I transition to the flooring in kitchen and to the left of the kitchen?

Again, thanks for all the input! I’ll keep posting updates lol. And Mowgli says hi everyone!
