Step climb departure best practices

Hi,

I'm looking for some guidance on industry best practices for managing step climb SID profiles with particular reference to vertical mode selection and armed/pre-selected altitude.

As an example of a departure, either the CPT5X or CPT4Y. Here's a link to the UK AIP page on Rocket Route https://fly.rocketroute.com/plates/a...7607&icao=EGWU

CPT5X description:
Climb to 3000, passing 700 turn left and intcp OCK VOR R011, cross LONDON CTR bdry/OCK D18 at 3000;
cross WATFO at 4000, then left on Tr 293° (BNN VOR R113); cross BNN D4 at 5000, then left on BNN VOR R284, cross HEN NDB at 5000; then left on Tr 226° (CPT VOR R046) to CPT VOR.
Would it be acceptable practice to set 5000ft and if managing the vertical profile in VNAV or 3000ft as it's the first step altitude? If using VNAV, In my departure brief I'd discuss TEM points, in particular the potential risk of not capturing the first step and for both crew to be vigilant for this at the key points and to manage tasks appropriately to facilitate this.

Thanks in advance
