Setting building help with intrigue and sci-fi

[weby]

For the feel of things an important factor are among other things:

How Transhuman the setting is, that is are there Intelligent AIs everywhere? Are people playing with human genes to build variant races and such?

How Cybertech it is? Is cyberware everyday thing people use to become better or just advanced prosthetics?

Is there immortality/very long lifespan? As in life extension drugs/rejuvenation and similar. And if there are how common/cheap/safe they are?

Can you take backups of yourself? As in your memories/skills and such that can then be easily transplanted somewhere.

Is there FTL travel and/or FTL communication? If there is how easy/cheap are they? IF you have ftl travel but no communication you will end up with a different things than if you have both. Also the different types of FTL travel cause totally different feels.

Is there gravitic manipulation? and again how easy/cheap if there is?

Is the overall world a bright utopia like like the Federation in Star Trek or Dysopian like cyberpunk

And so on, there are a lot of questions you need to ask yourself and based on the answers you can start to form the feel.

If you want a possible suitable hard science, but transhuman background then Transhuman space makes a good TL 9/10 setting with fairly much explanation of how the world seems to people living there. It could also be fairly easily adapted to secret struggle setting by having different factions controlling the major corporations and countries, it is a suitably balcanised setting to allow for many such factions to be placed.
