I can only make comments generally about standards--the first year or two the trunk is fairly vulnerable to sunburn until it builds up more bark--so if you have sunlight beating down, shade the trunk if you can the first couple of years.

The other thing, the standard always needs support--even when the trunk appears to have grown quite sturdy--a strong wind can still snap it off. Use a metal support rather than a wooden one--the wood supports tend to rot out long before you are ready to give up the standard, and they can be difficult to replace.

I have 'Brass Band' as a shrub. Great rose--somewhat slow to get going, but once established, a very striking plant.

Hope that is somewhat useful.
