Should I convert my traditional 401k to Roth IRAs to better estimate my networth?

Hi! I am switching employers and am trying to figure out what to do with my traditional 401k. My question is, should I convert to Roth IRA (pay the taxes now), convert to traditional IRA (pay the taxes later), or try to commence doing a Roth conversion ladder now? My biggest concern with keeping it in a traditional 401k is that I’m not able to accurately determine my net worth because so much of my long-term savings is pre-tax. I don’t want to think I’ve reached FI only to realize I still have to pay ~30% tax and have many more years of saving to go.

Anyone else been in this situation? Thanks in advance!
