Mobile Native, Crossplatform or PWA/SPA for streaming player?

Question

Mobile development

For an online player with a small base of audio lectures and insignificant functionality, it is better to make a prototype with a web face or a mobile client. If the first option, then how much audio can the browser cache on the device so that the temporary gap with 3g is less noticeable. And if the second option, then how to make such a client less bloody.
The priority is responsiveness to pressing the pause / play forward / backward buttons of the headset, will it not play the web native?
