What is the best way to create custom local delivery options?

[mertemin]

Hello, we have a store that requires custom local delivery options (e.g. next-hour delivery for $X, next-day delivery for $Y) and requires additional customization regarding regions (e.g. support certain radius for next-hour delivery). I started playing with deliveryProfiles API to see if local delivery options could be fetched there. That endpoint only support shipping profiles. Is that expected?

In fact, what would be the best way to approach this problem? Can a shipping rate support such use cases? I am a techie person, so I can build a custom app if needed, but need some pointers to get started. Any help would be appreciated.

I was playing with Parcelify as an example to see how that works. Interestingly, Parcelify (and I am guessing other advanced shipping customization apps) require Carrier-Calculated Shipping (CCS) so that all the details of an order can be sent to a 3P carrier and rates can be returned.
