Downstream rates are usually an order of magnitude faster than upstream.

I've heard of some municipal fiber networks the offer symmetric service, but that is not the norm, at least in the US.

You would have to check the terms of service of every ISP that might be part of the network.

Upstream speeds are increasing, Comcast is building out mid-split doing 100Mbps and 200Mbps up, and the other cable companies are doing network rebuilds for mid-split or high-split.

Fiber penetration is increasing every year, usually with symmetric speeds. Verizon FiOS is already fairly built out, CenturyLink/Lumen/Quantum is doing plenty of Infill, Ziply Fiber is part way through its 5 year plan to go from 28℅ fiber coverage to 85%, Frontier is actively building out fiber, etc

Wireless is only getting better too. Single Primary Cell Carrier Snapdragon x62 modems deliver up to 150Mbps uploads today, and newer Snapdragon modems can upload on multiple Cell Carriers at once (the secondary cellular frequencies they are connected to).

Ratios for upload fo download for asymmetric connections are trending towards below 10 to 1, rather than 20 or 30 to 1. The days of 1200Mbps downloads with pathetic 35Mbps upload are numbered.
