"getting called by best hand preflop"

When your size is large your range must be tight, you must protect your stack.

On the contrary when you expand your range you reduce your size because you receive:
-facing 3bet more frequently
- you need less FE
- pot control

From UTG and MP you can open 3x, co 2.5x and bu 2x.

If there are many fish you can increase your size and open fold marginal hands

A while ago one of the coaches used to split ranges.
For example,
if AA was A♣:A♦: he would min raise
if AA was A♠:A♥: he would raise 3.5x
If AA was anything else, he would raise 3x

I found it hard to remember what to do with what suits.

Another writer would change his open raise size by the second-hand on his clock:
0-5 seconds limp
5-20 seconds raise 2.5x
20-50 seconds 3x
50-59 seconds 3.5x

Another approach is to open-raise based on your opponents:
Raise more vs calling stations, less vs aggro players and so on

Me? I'm lazy. I just raise almost always 3x in cash games and early stage of tournaments.
mid stage of tournaments I drop to 2.2x
I'm almost never in the late stage, so I have no idea

We don't raise to get called by weaker hands, we raise to Steal the blinds !!

If they was no blind we would push AA and fold all others hands. UTG we can't steal to often because the probability of sucess is smaller so we have to do it with our stronger hands so we can open a bit larger.

AQs is not premium hand for me. When you guys watch high stakes tournaments like highrollers have you ever seen 3x from UTG ,no! This is about how you can deal with possibility of the hand postflop, so for me every open hand have same value ...

"We don't raise to get called by weaker hands"
With TT+, would you want people to fold?

We raise to get better to fold (a bluff) or to get called by worse (betting for value)

We often say post-flop that we're betting "for protection", but that is just a value bet made to make sure that draws have poor direct odds to call.
