You can defo do both OP.
To get breastfeeding off to a good start, get the right P&A support in the hospital, and bring baby to your breast within 30mins of giving birth. Ideally skin to skin contact (to regulate baby's heartbeat, temperature and breathing) but also to relax baby to know baby is safe with mum. Usually breastfeeding is initiated right away.
Plan for what you WANT to do, not what can go wrong; hospitals take care of that.
Hand expressing after day 3-5 is best to get things flowing at first, as you won't have milk established. It is colostrum at first (gold, sticky, small in volume) baby is best suckling this from your breast directly as colostrum doesn't transfer using express pumps very well; most of it gets stuck in the funnel etc.
Best way to build your supply; baby suckling on your breast. Their saliva stimulates your breast through hormones and messages to produce more milk. The expressing plastic machines can't do this. The idea is to build up your supply by 'feed, feed, feed' in the first 6 weeks. By 12 weeks feeds begin to regulate and settle down (this is when you notice your boobs lose the 'over fullness' as they self regulate). Interestingly, breasts always have 20%-30% milk remaining and never 'empty'. So even if you feel flat, if baby has all the feeding signs (see UNICEF or Breastgeeding Network), you have milk.
You can defo do both breastfeed and express; this can be great for some families. And you can choose to have days when you solely BF and days where you give expressed.
I would say keep the night feeds EBF as this is when prolactin levels are at the highest levels; (amongst other things) this is what encourages your body to produce milk.

I EBF and then from 6m, my daughter didn't need a bottle, she had water in a 360 sippy cup. Skipped bottles. However you can introduce a bottled when the suckling reflex is at its strongest (around 4-6 weeks) and they only have to have done it a few times to 'remember' what to do. Waiting past 8 weeks some mums find the baby has finished the suckling practice phrase and is moving to another oral skill hence why some mums say they won't 'take' it. It's because they haven't learnt how. I currently breastfeed and express while at work.
I would defo say getting the correct P&A support and info regarding building supply (bring baby to breast often in those crucial few days - you won't see the milk per say as it's colostrum and tiny in volume) but bringing baby to breast loads (every hour Ish) will establish your supply. Then you're off to a good start. Hope this helps.
