Which Civ:BE tile improvements provide benefits without being worked?

In Civilization: Beyond Earth, your cultural boundaries extend up to 5 tiles away from a city. However, the city can only work tiles up to 3 away from the city. You cannot build most tile improvements outside of your cultural boundaries, but it is possible to build improvements on tiles that are too far away to be worked by any city.

So my question is this: which improvements must be worked in order to have an effect? I know that Floatstone quarries, Firaxite mines, and Xenomass wells increase your strategic resource count even when not worked. Do any other improvements provide passive benefits?

Must a Dome tile be worked in order to provide +10 city hit points? What about its +2 culture bonus? If the +10 hit points does not require the tile to be worked, which city does it apply to if there are two equally-close cities? If it does have to be worked, does that mean that simply placing a military unit on an enemy dome will reduce the city HP, even without pillaging it?
Must a Biowell be worked in order to provide its +1 health bonus? What is the difference between "Provides" and "Yields"?
If there is a distinction between "Yields" and "Provides", does it mean that a manufactory provides +2 production even when not worked, and another +3 production when worked? If not, then does a manufactory provide +2 or +3 production?

Should I improve all tiles Civ 6?

While it may seem logical to improve every tile available, with the idea that the city will eventually grow into using them all, that's not actually the best idea. Just like everything else in a game of Civ 6, Builders cost time and/or resources to produce, and therefore should be deployed efficiently.
