This will get you a decent quality level of gear, easily upgradable.
The radiomaster pocket is an extremely solid radio, not just for beginners. it runs ELRS, which means it will work with any ELRS receiver or any drone with ELRS. (ELRS is the radio link protocol)
The air65 is primarily for indoors, but works fine outdoors. The air75 is primarily for outdoors, but works fine indoors (set a throttle limit). The meteor 65/75/85, mobula 6/7/8, and nimble 65 are also good options.
The eachine ev800d is the most recommended beginner goggles. They have diversity, which means it's using two seperate video receivers and picks whichever one is stronger to display in the goggles. The fatshark recon echos are the same price, with higher build quality but no diversity. The skyzone cobra sds are a nice pair of intermediate goggles. These goggles are analog, which means any drone with an analog vtx (video transmitter) will work with them.
The vifly whoopstor v3 is the best 1s (1 cell) charger on the market. Cheap and reliable.
The BetaFPV lava 1s batteries are the same as the tattu, webleedfpv, dogcom, newbeedrone, and tinywhoop (brand) batteries. It doesn't matter which ones you get. anywhere from 260-450mah will be fine. I run 400mah on my 65mm tinywhoop.
