I’m a WHM main since ARR, and I do find that WHM is less thought about compared to other jobs. It’s been kicked out of Meta for multiple expansions since AST was introduced. To compensate lack of utility, we were given the damage contribution instead, however raid groups will always take a healer that buffs a party… increased overall party DPS is always better than an individual putting out a slightly higher DPS.
This can be seen in the first clears of this raid tier. AST and SCH were taken over WHM and SGE.

I’ve done P1S, i have a SGE for a healing partner. It’s the first time since ARR where another healer job has been above me in DPS. No matter how many glares I do, the SGE can cast more than I can in a fight, even when being less active. They are way above me (all be it i’m not overmelded either but still). Is this down to how quick it’s casts ? The number of OGCDs it has? Or that it doesn’t need to worry about mana management at all?

IMO WHM needs to be balanced to match SGEs healing and DPS capability. They should be on parr with each other at least. SGE is on top for both at the moment. WHMs mana regen is also needed to be looked at - you know it’s a DPS loss when you need to start melding PIE just to make things more comfortable.

I love lilybel. It’s great on bleeds and multiple AoE hits. Maybe having a shorter cool down may help? Or have it do damage as well as heals?

WHM needs something just to make it as desirable as other jobs, I love its not changed to much… but it just needs something.
