In all likelihood, a rider like yourself isn't too far from being as fast as a typical cat4, weekend group ride club rider. You just need to sharpen up that high end/short effort fitness, and gain a little bit of skill.
I know you ride a fair bit, so your basal aerobic fitness and maybe even FTP are probably decent at worst
