The best iPad for value and features is the 2019, 10.2 inch screen iPad 7th generation.
As an example and compared to your older iPad,
The baseline 2019, 10.2 inch screen 7th gen iPads have a 1/2 inch larger retina screen, newer, more powerful and nearly 2-1/2 times faster 2.3 Ghz, A10 Fusion processors, AT LEAST, 3-4 times the internal RAM, with the 2019, 7th gen iPad having 3 GBs of internal RAM, iPadOS 13 support, with much better and improved multitasking features, Apple Pencil and Apple Smart keyboard cover support and have better audio speakers and better/improved built-in cameras.
Also, the 7th gen iPad runs THE EXACT same iPadOS 13 with every software feature all other newer and better, more expensive iPads run!
Also, if you search other online sellers of this iPad model, you can save, at least, between an additional $60-$100 depending on the seller and the device storage model ( 32 or 128 GBs internal storage models).
If you can, you do not have to pay Apple's own pricing on the 2019, 7th gen iPad.
Best of Luck to You!
