A well estrogenised vagina shouldn't really need any additional products - were you moisturising it when you were 25?
However it is very difficult to maintain urogenital health with vaginal estrogen alone at the doses commonly prescribed, so if this is all you have access to I would start by using it daily if you are not already.
If you really do need or want to use an additional moisturizer, choose one that is designed for intimate use, ideally with as few ingredients as possible - none of those substances would come into contact with our genitals naturally.
Also you need to make sure that any fungal infection you may have had has actually been fully cleared, so I would suggest getting a further swab and maybe see if there's a local sexual health clinic that you could go to without a referral if there is nobody with an interest in female health at your GP surgery.
