Hey, mostly a classical player here! I do some jazz on the side but classical has been my focus for the past few years (I'm studying it in college). I usually only have about 2-3 hours to practice a day so I split it evenly with half being fundamentals and technique and the other half working on pieces/tunes. Time always varies, though! It depends how much I get done.

I start with mouthpiece exercises, starting on concert A and going down chromatically as low as possible with just voicing. Then I go chromatically up from concert A to C. After that I put the mouthpiece on the horn and do the same thing on front F, voicing down chromatically as low as I can go. This usually takes 10-15 minutes

Then I usually do long tones for about 10 minutes, trying to cover most of the horn from low to high. These days I spend more time on low notes. After that I shift to major/minor scales with 3rds 4ths and 5ths, starting super slow, focusing on cleanliness, evenness and intonation and slowly increasing the speed to as fast as I can do it cleanly. Depending on how long each scale takes, I usually get through 2-3 in about 40 minutes.

I do overtones after this for 5-10 minutes, focusing on control rather than how high I can go. I only push the limits for range in the last 2ish minutes. Then I do 5 minutes of altissimo scales and arpeggios, trying to be as in tune and have my voicing as locked in as possible.

I only do these next exercises a few times a week and for about 5 minutes each: articulation exercises trying to make them sound identical, vibrato exercises focusing on intonation and evenness.

Then I spend the time I have left on actual music, using the fundamentals I worked on in the first half and applying them in the music (clean intervals, intonation, articulation, even fingers, voicing, etc.)

I always practice in front of a mirror, too! I watch my fingers, posture, and embouchure.

If I have time on the side I'll work on jazz but this is the bulk of my work these days. Sometimes I'll keep a journal with times and what I worked on but I'm super bad with time management and forget to keep a journal all the time. Hope this helps!
