Can we talk about discount rates (CAPM/WACC)?

So this is something that I think about but can never narrow down how I actually think so thought I would come here...

What do people use for discounts rates? I use CAPM/WACC but I don't like it yet I don't know what to use an alternative. At the same time, if the rest of the market still uses CAPM and I don't, then I still need have a valuation that the rest of the market will inevitably arrive at and valuations are sensitive to discount rates.

So what's everyone's process/philosophy regarding discount rates? How do you approach it? Would love to hear someone's thought process to help educate me and expand my reasoning! Thanks!
