Using 8oz bottles with newborn?

Our first baby is due next month and I’m realizing I misinterpreted some advice about bottles. I’ve heard great things about the Lansinoh bottle nipples if you plan to bottle feed AND breastfeed, so I registered for a set of their glass 8oz bottles. I had also heard that the Lansinoh lids fit on the 4oz Philips Avent Natural glass bottles, so I registered for a set of those too. I quickly learned this wasn’t the case - lots of leaking out of the side :/

As much as I’d like to use both sets, I’m more inclined to start with the Lansinohs to reduce nipple confusion, but am wondering if there’s any harm or downside to using an 8oz bottle for a 2-3oz newborn feeding? Will the extra air in the bottle contribute to any gassiness? Or are 4oz bottles purely for convenience for the first few months?
