Wired Coax Connection vs "Wireless" Fiber Connection

I have been considering going to a Cox fiber connection to the home to improve speed/quality.  I currently work out of the home where I have a hard wired connection in my office via coax.  Unfortunately it will not be easy to run ethernet to the office,   So my choice is to stay as-is with what is now a 500/10 Mbps coax to the home connection or upgrade to fiber with speeds of either 500/500 (unsure of upload max) or Gigablast.  However, if I go fiber, then the connection will end up going to another end of the home (not my office) and that I'd be forced to work in my office via a wireless connection.   I've looked into Wifi 6 mesh systems like Asus XT8, Orbi, Eero Pro 6.  I thought about placing one of the satellite mesh nodes in my office and then hard wiring to the node.  I would still be relying on the wireless backhaul connection between the main wifi mesh router to the secondary node.  So my question is whether it's worth it to be on fiber?  I'm not dissatisfied with my current setup (coax) but wouldn't mind faster upload speeds.  Any thoughts?
