I searched through that website to try and find any concrete proposals, but all of it seems to be aspiration. That's fine, the project isn't going to start for 2 more years, but if you're going to propose a bunch of stuff to the public, I thought you would want to have a purpose/need you want to fulfill. (I'm talking specifically about the transit center - they don't even know where they want it, which is super weird.)
I like the idea of floating bus stops and buffered bike lanes. I don't think we need a full "Bus Only" lane, since we still want local and express buses. Buses stopping in the travel lane would be a huge improvement on its own, and the bus priority signals would be super next-level without the need for bus only lanes:

(youtube video from the website)
The video shows a bus in a bus -only lane getting priority through an intersection into a shared lane. This would also work just fine with a BAT lane (Bus And Turn lane). The bus would get into the right turn lane. The cars ahead of it in the lane would turn right on red, leaving the bus at the front of the line. If the bus wasn't in the front of the line, a green arrow for right would also be used at the same time as the bus priority light. That way the bus can get around stopped cars. It would also be the ideal place to put a sheltered bus stop, since the right turn lane is close to the curb and wouldn't take up any extra parking spots.
