Having now listened to that portion of the podcast, I can say with certainty that you are focusing on only a single part of what was said and are missing the intention of the statement by doing so.In the podcast at 12:35, Crawford says that if a spell says to choose something (a creature, object, a point in space), whatever you choose is that spell's target. That's why I say that teleportation spells target the location, because it's the only thing in the spell you choose. Bring it up with him! Cheers!
Edit: also, it's Sacred Flame that ignores cover, not Flame Strike.
Specifically, just prior to the time you mention, Crawford says that targeting is when "you choose someone or something to be subjected to some kind of effect."
You are latching on to the following comments which, given context, are attempting (however poorly) to build upon, not contradict, that statement.
So you don't need to house-rule anything, because not literally every choice made within a spell is choosing a target - just the choice as to who or what is being subjected to the effect of the spell, which in the case of teleportation types of spells is not the location to which the teleportation will lead.
