Parquet Floor Advice

Discovered a parquet floor underneath a rank carpet. It looks to be in good condition, except some damage around the edges where they've nailed in the carpet grips. I don't know where to begin. As of right now I just want to get it safe and clean, and perhaps it can be fully restored by someone if we sell on or by me if I decide to stay there permanently.

I'm happy to do what I can myself, and I'm wondering if anyone can offer some advice or point me to some resources that would help?

I know Google exists but I'm essentially moving out ASAP/mid separating and up to my eyeballs with everything so hoped someone who has already done the hard work might be kind enough to share their knowledge with me here so I can multi task. Much appreciated!

Finding this was a bit of a highlight tbh!
