On the Quest avoid 600 & 601. Anchor noise significant. The front windows open to the public deck. They have a one way coating but it is still rather creepy when folks are looking in. You'll only make that mistake once. π
If you Google the specific suite, you can often find numerous videos of that suite. Perhaps you have already found some. Use the category name, not the suite number. Remember that the Quest, Sojourn, and Odyssey are sister ships. Rooms and spaces will be very similar.
Specific questions about what is or isn't included can only be answered by the cruise line.
In general suites near the bow will have the most motion, aft, less so. Center, significantly less.
Good Upgrades get snapped up fast.
