BetterTouchTool has also recently added full Logitech support (keyboard & mouse) and it has been working great for me. (Fully replaces the Logitech Options+ and/or Ghub apps).

Especially the smooth scroll modifier available in BTT (not exclusive to Logitech mice) has helped me a lot, it transforms any mouses scroll events into trackpad like scrolling events that allow for e.g. page swipes, mail archive, scrolling in calendar etc. - things that usually only work with Magic Mouse or Apple Trackpads

BTT also has nice gestures support for this which is a drop in replacement for options plus.
