Which CRM allows auto-filled fields on its form?

Hello again!

I'm looking for a CRM that allows file uploads and auto-filled fields (from URL/button click) in an html form.

Salesforce forces me to use a .force website (for file uploads) and Monday simply doesn't allow pre-filled fields.

Freshworks CRM looks like it does what I need but I'm so run down from trying multiple solutions that I thought I'd just ask here.
