I'm pretty mediocre on each spectrum, but still I would be interested to know.
Instinctually I think I'm slightly more on the fast twitch spectrum because I can crank out a 65-66 sec 400 with very little, almost none, training. While I needed quite a long time (25-30mpw for a year) to run a 21 min 5k.
Again, I know I'm quite mediocre, but yea I just want to know.

Have you ever run a 100 or 200 from a standing start? While a 7’7 broad jump isn’t anything spectacular, it’s above average and would suggest better speed than a 65 sec 400m would indicate
Am curious what your 100m and 800m times are. Not sure on what basis most responses here are confidently saying you are unlikely to be fast twitch, but it’s not something one can accurately say without fiber composition analysis, and to the extent one can guesstimate, you seem more likely more fast twitch than average as your 5K time is much slower relative to your sprint times, but that could also simply indicate insufficient endurance training.

While 7'7" is a better than average jump it's not impressive for a sprinter. Yeah he might have better fast twitch than the average 5k runner but he wouldn't be selected for the sprints. I used to measure jumping ability in my PE classes and quite a few had 9' and above SLJs. These were the sprinter/jumper/throwers. The 6' jumpers were the non athletes or distance runners.
Of course we dont know his height, weight, experience with strength training and as you stated endurance training.
If he were on my team as a 9th grader I'd probably start him out in the 800.

I actually think the 800 or some sort of middle ground is a good call. 65 off nothing in sneakers could become a 56 or 57 with spikes and a few months of speedwork. 21 minutes isn’t stellar but again it could still come down a fair bit. At least then you are training multiple components of fitness and can get a taste of how you respond across those components.
Power can be very improvable - my baseline standing long jump was only 2.4m (8ft) aged 19 off of a few years of 5k training and I got it up to 2.9 (9’6) in about 1 year (and a 13.2m triple jump a little later). I seem to be about equal in endurance and power capacity (16 low 5k as well previously), but possibly slightly more suited to dynamic strength events (Javelin comes somewhat naturally and so does jumping to the extent that it is limited by my speed.
A 10.3 runner from my club can do a 3.4m STJ without much jumping practice. I’ve got a spreadsheet of all my youth athlete’s standing long jumps and they do correlate, but not perfectly predict their current ability in the sprints and jumps. I think STJ is a good measure of power for the trained/aspiring power athlete but I don’t think that metric will necessarily tell you much about fibre composition at a beginner level if the athlete lacks coordination and a strength base.
There are fast twitch mammals and there are slow twitch mammals. Humans are slow twitch mammals. Biologists will tell you humans have three different type of twitch muscle fibers. Scientists label them falsely as fast twitch combination twitch and slow twitch. Humans actually have three type of muscle fibers, slow, slower and slowest twitch. Compared to other mammals, our comparative advantage is endurance.
You cannot define yourself by muscle twitch. You are not going to get an answer: Wow! 65 400m on zero training thus sub 45 400m with training. Also, no one can correctly state because it is not easy for you to run sub 21 5K then you are incapable of racing sub-17 5K.
Out of the 69 sub-27 10000m men and 8 sub-27 10K men on the roads (is there overlap?), I am sure many of them are sub-50 400m men, most, sub 52.5 400m men and I am sure all sub-27 men are sub-55 400m men.
Do what you like doing and and chose the activity or sport or event in which you possess a comparative advantage to your peers.
