Internet upload speed
My plan is 400/100 but I'm only getting 400/10 speed. I'm using Netgear CAX80 with docsis 3.1. Why am I not getting 400/100? Also, the xfinity assistant is purely useless.

The CAX80 is not one of the few retail devices approved by them for the higher upload speeds. See https://www.reddit.com/r/Comcast_Xfinity/wiki/knowledgebase/next-generation-internet/ and https://www.xfinity.com/support/articles/upgraded-areas-leased-equipment-required-for-upload-speeds. Also see the "All Compatible Devices" link near the bottom of https://www.xfinity.com/support/devices (at the moment it points to https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2023.11.22%20Full%20List%20of%20Compatible%20Devices.pdf).
Certainly, it leaves much to be desired.

Realize that although Comcast calls some devices "Approved" and some "Recommended", for all but a few devices those designations only mean "approved/recommended for use with their Internet service", and not "approved for the new higher upload speeds". For that, you need one of the devices shown with an upload speed rating in the .PDF and the Reddit links, which also lists other requirements for those speeds. Comcast could make all of this much clearer, but they have chosen not to do so.
Since they do not usually announce new approvals ahead of time, your only choices are to either wait until such time, if any, as they approve the CAX80 for higher upload speeds, or to purchase one of the few models already approved. They rarely tell us what's in the pipeline except in very general terms.

Greetings, @user_v37nfr! It looks like @BruceW provided you with the best information we have on what customer owned and managed devices are approved for our Next Gen Speed tiers. We are continuing to work with manufactures to have more devices added to the list in the future.
