UUIDv7 looks interesting, but how is it different from ULID [1] in practice? I was considering using ULID for a upcoming new project because it is lexicographically sortable but it looks like UUIDv7 just can replace that.

As the author of a popular ULID implementation in python[1], the spec has no stewardship anymore. The specification repo[2] has plenty of open issues and no real guidance or communication beyond language implementation authors discussing corner cases and the gaps in the spec. The monotonic functionality is ambiguous (at best), doesn't consider distributed id generation, and is implemented differently per-language [3].
Functionally, UUIDv7 might be the _same_ but the hope would be for a more rigid specification for interoperability.
