Pretty chill, a little introverted - I love conversations but I'm not great at starting them.

i know u already mentioned that it's "not great," but i strongly suggest that u remove this single sentence that is ur self summary. i am a motor mouth and 1 of the 3 skills [i know it's sad i should have more skills] i have is starting and maintaining conversations, but even i was like "grumble grumble next...."

so it seems like u r a standup guy with some well-rounded interests but u r coming off as bland to me. ur profile is concise which is good. i suggest that u think very carefully about how ur wording might come across to a potential mate:

I have a job that involves doing a lot of staring at computer screens, so I try to moderate how much of that I do outside of work.

i read: i have a meh job that i feel meh about that i try to get away from as much as i can.

I recently got back into cycling and I'm pretty excited about it.

i read: i have a newish hobby that i am moderately interested in for reasons that i cannot bother to articulate [why add "pretty"? it dampens the excitement. also, that u r excited about a hobby tells me nothing about u, esp. since cycling as a hobby isn't surprising given ur other hobbies. if ur other hobbies were knitting and philately, then the inclusion of ur excitement about cycling would be informative.]

I'm also always looking for more interesting things to do

i read: i am the same as everyone else [this is something that a lot of people say and not everyone means. if this is something that u believe truly defines u, give the reader evidence to believe ur claim. e.g., how do u go about looking for interesting things to do? what is ur definition of interesting?]

I like books about things I'll never experience and books that open me to new experiences.

i read: i read books b/c books have stuff in them i don't know about [maybe u can expand more on what draws u to scifi more instead? e.g., the genre challenges us to think carefully about X]

ur i spend a lot of time thinking about section made me smile--it gave me a sense of your sense of humor. perhaps u could try to include that version or aspect of yourself in the other sections.
