Oak architrave and skirtings

[Moonshine]

 

I am having oak solid core doors my build, door style to be decided, i was going to have standard white architrave and skirtings, until my good lady highlighted that oak looks a lot better, as below i can see her point.

 

 

I now wanted to go down the oak architrave and skirtings route, i am sure that the cost is going to be painful but worth it for the look.

 

Do people go for the solid oak or veneer? also what are the tricky bits with installation vs traditional white architrave and skirtings, i presume there is no hiding gaps with decorators caulk and paint.

Oak veneered MDF from Howdens, longer lengths than real solid oak, cheaper, won't warp or crack.
