I mainly use ranger, or some conveniece scripts I've built around ripgrep, ripgrep replace and fd. When i find the file i want I either open it directly to do a small chance or use the fuzzy search in my long running session to open the file.

The only thing I haven't nailed yet is creating files in deeply nested directories.

In general most of the things I used in nvim have now moved back to the terminal which has its pros and cons.
