Salam all
Personally brother Ahmad, from the ayat you've quoted above, not a single one implies that Allah swt is located in a physical volume.
For 67:16-17, when you read on to 18... (especially 18) Allah swt talks about people who denied His signs/messengers etc. So the part in 16th ayah you mentioned (Allah swt knows best) is some sort of a "reply" to deniers in their own expression. Maybe they addressed Allah (swt) like "The one in the sky" so it is possible that Allah swt replied them and asked a question to them with this adscription they used. It could also be a metaphorical usage of these words to show His sovereignty, exaltedness (not necessarily a physical location).
For 30:11 it doesn't imply a place, location, Allah swt simply says that we are to return to Him. When i say: "I know she will come back to me soon!" do i imply a location ?
For 2:115 is metaphorical, He sees you, hears you, knows what you do , what you feel, wherever you go...
For 6:3 please read the sentence carefully: It's not "Allah is in the heavens and the earth" it is "
He is Allah in the heavens and the earth". They are totally different. He is the One and Only God, Allah, for all beings in the heavens and the earth.
For 57:4 it's just another way of saying "He is well aware of you wherever you are". Just like 50:16:
"And We have already created man and know what his soul whispers to him, and We are closer to him than [his] jugular vein" (50:16)." Such a wonderful statement subhanAllah. Obviously that doesn't mean He is right behind our jugular vein

He expresses His closeness, His connection to our souls.
Allah swt knows best and may He guide us if we are wrong in our thoughts and actions.
Take care. Salam.
