In regards to "tracking": small dark pool >>> large transparent pool
You can't use amount analysis on Monero like you can with Bitcoin because they're hidden with CT.
Receivers are also unknown unlike Bitcoin because of Stealth Addresses. They could be any Monero user that has ever existed.
Your IP is also hidden from other nodes on the network thanks to Dandelion.
So all this traffic size talk is moot when your traffic is fully exposed
