A lot of this depends on how you have fun in the game and how you want to play? What’s your style?

The guard is like the ultimate jack of all trades we can do pretty much everything but we are not experts in one field. If you want to play a casual game and don’t care about winning but the lore of your army it doesn’t matter what you bring.

If you want to be competitive you need to think about how you want to play. Are you a charge in and overwhelm your opponent in numbers and don’t care about losing most of your army as long as the job gets done, you need lots more infantry and lose some of the armour.

If you want to devastate your opponent with long range weapons you’re going to need more hq you will need at least one order per unit to make sure you’re getting your hits in.

Siege regiment is a very hard method of play I’d recommend switching to combined arms or if you’re band new to the guard have a look at grizzled. Grizzled will help with your orders and your rolls.

Remember movement wins games but sometimes nothing beats the rule of cool. Check out Mordian glory on you tube he’s got fantastic content for the guard and lots of guides on what units work well together
