Using a column date from sheet A to populate a dropdown in sheet B (Non data shuttle)

I'm looking for a way to populate a drop down automatically from data entered into a seperate sheet.

We have a central "New Projects" sheet which acts as master data sheet. Several other sheets use forms that have a dropdown to choose the project, where the dropdown data is taken from the New Projects sheet. We have until recently been using data shuttle. Apparently we've used some 2m plus rows (no idea how since we only have roughtly 100 active projects and filter in active). Smartsheet are now looking for extortionate sums to allow us to continue using Data Shuttle, and I don't believe we should be paying $10k's for a massive gap in functionality!

I have access to Zapier, and Power automate, so would welcome any suggestions for a work around, please.
