What do you do in a max technology game (with no intel allowed) with those planets that have no resource production Category over 100%? I usually use them for intel or research, but in this case there is no point in that strategy. Should I just stack them with value improvement plants and wait until they are usable for resource extraction?

Those would be good places for system-wide bonus facilities (including happiness facilities and the population bonus facilities from organic or religious racial traits), space yards, space ports, system shield generators, training facilities, resource conVersion facilities, the "recycler" facility (the one that provides better return on scrapped vehicles) and resource storage facilities.
