Question About Patching macOS For 2007 Macbook

Hi, I just recently got an old 2007 Macbook which is limited to macOS Lion but I heard you could patch it up to El Capitan. Will El Capitan run alright or would something like Mavericks run better due it having the older design design? I would like to run 10.9 or above because thats the oldest macsOS version that is supported by Firefox 78.
