If you haven't done so already, I'd recommend you do a search through this part of the forum as there's a lot already discussed on this topic as well as some ongoing threads about alternatives. And there's definitely more than just Capture One, a good summary of options available are identified here:

I haven't read all of the blog post so I don't know what's being recommend, but like many things finding agreement on the best choice for PP is not likely to happen including the PF suggestions you will hopefully receive soon.
Personally I moved from LR/PS as my primary PP software to On1. It's not perfect but it has a lot of the tools you would be familiar with from using LR/PS. The current version is really good and it's yours to own, though in about 12 months there will be a new version and a final update to the current program will be released. You choose to update or not and to update every year would equal similar costs to a subscription. My plan is to do one more update then sit out a year or two.
Considering you've dropped out of CC and as there's plenty of options the best course of action would be to utilise any free trial periods offered to see what suits you.
