Even with more information about the specific bars you are considering, nobody can answer the question of comfort except you. Handlebars are a very ‘personal’ choice and should be based on what works best for you. The only way to figure that out is to try different setups. Wether they all match by brand is a pointless consideration. If you’re hung up on brand, I would suggest you let go of that. Buy whichever set of bars you think will work best for you, regardless of brand. If they don’t, change them. Having a professional bike fit, can help make this determination, but it’s still up to your individual feelings. Experimentation is the only answer to your question.

as far as pedals go, that largely depends on how you feel about having to wear cycling shoes and dealing with clipping in and out. How often will you be riding more casually vs how often will you be riding more aggressively. That’s what I would consider. Based on the limited information given though, my gut instinct says you’d be better served by a set of flat pedals with foot retention, instead of clipless.
