This is not a simple question at all and there is some different concepts to consider especially playing from the blinds.
So in general over all positions the betting frequency oop will drop down usually (positional disadvantage discourages thin valuebets).
So you are right in general that we bet less often and with a bigger sizing OTF.
This will be somewhat different OTT/OTR, but might be a different topic.
Frequency and sizing is usually dictated by rangeadvantge (frequency) and nutadvantage (sizing).
So SB vs BU is a bit special as we will play a kind of tight linear range vs a fairly whide BU-defends range.
So from a theorypoint we will be able to bet a lot of boards on a high frequency and small sizing.
However: the sizing you picked on this particular board is fine as BU should have more 7x/4x/56s/89s and maybe Jx as well that we lack off. So our rangeadvantage drops a bit and we will bet less often and a bigger sizing.
Last note on this: If we 3bet from the BB we usually 3B a much more polar range and thus our betting strategy will be often much more polar as well (ie lower frequency and bigger sizing).

I am betting 100% of the time here SB vs MP on this texture. I am also using the big sizing. I can't stress how important texture is here. On a J87 board, I would start to introduce a lot more checking.

What does your range look like here? Most pools are 3 betting between 4-5% from SB vs MP. That boils down to pure 3 betting TT+ or JJ+ and AK. Mostly 3 betting suited broadways and some AQo. Maybe including some A5s/A4s. We are very tight in this formation.

What does MP call range look like? Probably mixing JJ as a call, pure calling TT to 66 maybe, they call too many connectors.
