SharePoint Server migration to SP Online with lot of form library

Hi!

I would like to ask some experience, best practice for SharePoint migration:

In SharePOint Server 2016 we have a lot of InfoPath form, over 300 item in form library:

• if there are contents that just need to be read in SP Online,  I don't want to transfer them to a list and Power Apps, how can I fo it? 
• has anyone used a good migration tool from InfoPath to Power Apps?
• if you didn't migrate to power apps, what solution did you choose?

We have a more than 280 workflow, I read the SPMT can migrate workflow to Power Automate:

• does anyone have experience with this, does it work well?
• or other migration tool (free preferred)

Thanks :)
