By 1st playthrough, you mean going straight to the final boss and skipping ALL of the other content in the game, including additional content that unlocks after beating the final boss. Most people who play Super Mario Odyssey aren't going to go straight to the final boss and consider the game done and be ignorant of all the other places there are yet to go to in the game. If you want to skip content and call a game short because of things you are purposely ignoring, then whatever floats your boat.

1st Ending
From my experience it takes roughly 9-10 hours to reach and beat the final BOSS and unlock the 1st ending. This is based on an average players skill.
Players only need to collect approximately 120 Power Moons to complete the story.
I would expect that experienced Mario players could knock that time down to 7-8 hours and speedrunners could take that down even further.
100% Completion
The estimates above only count the time taken to reach the 1st ending and do not consider the end-game content or 100% completion. Unlocking the secret kingdoms by collecting the milestone 250 and 500 Power Moons will take you considerably longer
In my experience again, it can take at least 30 hours to hunt down and collect all 800+ Power Moons to reach the 100% achievement. This includes beating the BOSS rematches and conquering the "Champions Road" challenge.
Choosing to go after the remaining moons opens up a tonne of new content that allows you to enjoy the full experience of Mario Odyssey. I strongly recommend that everyone venture down this path after beating the story.
