So I´ve had this discussion with some DMs, and after looking around for an hour, with the sage advice of J.C., and I quote: "Unarmored Movement is intended to increase a monk's innate speed, including an aarakocra monk's flying speed." we have concluded that the Fly spell, Ring of swimming, Boots of flying etc. do not benefit from innate speed increases like Longstrider, Mobile or Unarmored Movement.
However, some argue it the other way around (as it would affect their builds). We´d like some more people discussing this, so I have decided to post this here to get some more opinions from other DMs.
Changes to Your Speeds. If an effect increases or decreases your Speed for a time, any special speed you have increases or decreases by an equal amount for the same duration. For example, if your Speed is reduced to 0 and you have a Climb Speed, your Climb Speed is also reduced to 0. Similarly, if your Speed is halved and you have a Fly Speed, your Fly Speed is also halved.
So, for the example of Longstrider which states that "The target’s Speed increases by 10 feet until the spell ends", if you also have a Fly speed then it also increases by 10 feet until the Longstrider spell ends.
The Fly spell states that "For the duration, the target gains a Fly Speed of 60 feet".
Perhaps annoyingly, this appears to be an order of operations issue. As written, the increase imposed by Longstrider happens at the moment that the Longstrider spell is cast. So, if Longstrider is cast on a target first and then the Fly spell is cast on that same target later on, the Fly speed granted by the Fly spell is unaffected. However, if the Fly spell is cast on the target first then the Longstrider spell will affect both speeds.
I think it should be treated like AC is: you have a base speed, plus abilities that increase it. If you have a ring of protection on, and cast mage armor, you still get the ring's bonus. Similarly, if you gain a fly speed of 60, your already existing Longstrider bonus is added to it.

In case it's helpful, the Dev also clarified this related to that conversation:
@JeremyECrawfordBonuses/penalties to speed apply to your speeds in general, unless the text specifies walking, flying, etc.
Any bonuses to you speed that don't call out a type (walk, swim, etc.) should apply to all of your speeds regardless of the source (innate, spell, etc.). If you have more than one source of a speed, they do not stack, you only get one of them. For example, if you have an innate fly speed of 30 feet, cast Longstrider on yourself, then your buddy casts Fly on you , your maximum fly speed would be 70 feet (60 from Fly +10 from Longstrider. The lower speed from your innate ability would simply be ignored.

According to the Rules Glossary entry for Speed:
So, for the example of Longstrider which states that "The target’s Speed increases by 10 feet until the spell ends", if you also have a Fly speed then it also increases by 10 feet until the Longstrider spell ends.
The Fly spell states that "For the duration, the target gains a Fly Speed of 60 feet".
