I think people are misinterpreting the score cap.
The cap is 1mm (million). That means every single song played 100% perfectly will give you a score of 1mm (plus modifiers, plus spinner score).
Every song played perfectly with one note missed at the start will give you less than 1mil (if no mods or spinners) but depending on the amount of notes in the song the difference between the score and 1mm will be larger or smaller. Songs with a lot of notes will have a higher score than songs with fewer notes for example.
Full combo still matters since as you go up in combo each note hit is worth more than the last in a quadratically increasing manner just that the amount of score you get is normalized to 70% of 1million for a full combo.
If you played a marathon song today that has 2000 notes your score would be pretty gigantic. The only difference the score cap does is normalize the maximum score to 1mm. Due to the weighting of combo (70% of score) and acc (30% of score) you can't directly compare scorev1 to scorev2. You can make scenarios where you could compare them though. If (pretend fail is off but no 0.5 modifier to score) you had a long map with 1000 notes and compared the ratio (low score divided by high score) of a 100% score to a 100% score that missed the first 50% of the notes, the scorev1 and scorev2 ratios would be the same minus some rounding error.
I wouldn't say the score is capped to 1 million but rather that your final score is normalized to 1 million. Relatively and proprotionally unnormalized vs normalized numbers remain the same.
Let me know if I've misinterpreted the scoring system though I only gave it a cursory read from the first post here (t/375428)
