Trying to find some recommendations for tile sets that contain modern, future, and space assests. I'm open to getting specific symbol sets or the annuals they maybe in.
Focussing on the Cartographer's Annuals in this response - most recently this month's edition of the 2022 CA (Electronic Systems) might interest you. https://www.profantasy.com/annual/2022/2022-cartographers-annual.asp#May I mentioned this one issue specifically because I haven't updated the annual links wall to include it just yet, but the majority of all the rest of the annual issues can be browsed from here:
There are other add ons and packs, including Cosmographer, which might also be of interest.
CSUAC2.0 and Dundjinni Archives also have plenty - see cartographic resources category on this site
There is the Modern Symbol Set 3. It feels more like 2000 modern than contemporary modern to me, but it could work for you.
Cosmographer and annuals are it for futuristic. Annual 6 may be a good one to look at.
