Axs should be an open from all positions 100%, if you understand when to F cbet and T cbet as a bluff.
Let's take a look at what do people play at microstakes and how we an exploit them. I see that many fun players love to play prety cards - 78s, 89s, J9s, 64s. These cards are hitting flushdraws and straights and they kind of battle vs our TP type hands. Now, let's come up with a preflop strategy how to beat them. We open all Axs hands which really dominate those hands and hit the nut flush over a smaller flush.
As for bluff part. F cbet backdoor FD's and barell OTT (OOP) when hit a FD. Bet OTR when hit flush, otherwise give up. IP just take a free card at micros (consider ranges if turn bet is OK).
We win from FEQ + EQ and thus don't need to over do it. (Remember, just because Villain didn't fold this Flop, doesn't mean that this F cbet didn't make you money in a longterm. 100x these flop cbets, or turn cbets are required to see the results.
Then again against some opponents different lines are more +EV. cbet flop, x/r turn - vs floaters (when he bets a lot vs missed turn cbet and din't fold to F cbet). And vs regulars (somewhat adequate) i x/r balance (not GTO, because I'm too strong anyway) my nutflush draws vs my sets on boards like 976tt, 732tt, etc. I don't intend to fold to raise though and often look for some straight outs ax well. Like Ah7h on 8h6h5s. (This line because I x/f most of my overcards and expect Villains to be unbalanced with Flop bets.)
