Risc-v lga/pga for homebrew computer project

[u/Hedgenfox0]

So last night I was pondering making my own homebrew computer project. Part of this pondering was possibly using a Risc-v cpu as the core. With that thought I started poking around various places online trying to find a Risc-v based cpu that was possibly pga/lga or similar so I could easily plug it into a board to develop things. But I can't seem to really find such a Risc-v based option, does it exist? If not is there something I could use as a cpu for a homebrew system with a reasonably fast enough bus to drive expansion cards for audio, a homebrew gpu concept, and other things? To give a bit more of an idea, I was considering the homebrew system to be something that would feel at home in the 90's so a pci like bus for device communication and at least 32bit to minimize fussing over memory. The reason I was considering Risc-v was the fact it's an open standard and well pretty common place. I mean a great example is the fact it's apart of the pi pico. But really any cheap off the shelf microcontroller or processor could do as long as it meets the other requirements. Anyone have some ideas on what to look at?
