Does legroom matter?

Hi! I just started my airline and wondering if legroom matter in this game…
There does not seem to be an obvious answer to this in the game

No, legroom does not matter. Try to fill up your cabin configurations to the maximum and use the most basic seat type (basic Economy, basic P. Economy), etc.

Then I’m guessing service is what really matters?

Service (IFE + IFS) affects your flight reputation, in conjunction with the flight time (longer flights have higher passenger expectations). higher reputation allows you to raise ticket prices without losing demand.

Also, legroom is represented by seating type. The amount of seats you have is adjusted appropriately with legroom in mind.
