Web interface for a slow connection - what to choose?

Question

Frontend

The task arose - to make a web interface that will be used on mobile devices in remote areas with an unstable and slow connection. Basically, you need to send data through a form, but you also need to display tabular data with a volume of 100-200 lines. The implementation options so far are seen as follows:
- bare html in the browser
- use of any front-end framework (Vue, React) in the browser
- framework in PWA
- AJAX on bare JS
- your option?
Which of the options will be the most efficient in terms of performance?
