SharePoint Modern Page Connetion --> text to list

Hello SharePoint Community,

My scenario: My organization just upgraded to SharePoint 2019. 

How I had it previously:

I just recreated my pages it in the new environment in classic pages, but the handy https://platinumdogs.me/2014/02/12/showing-sharepoint-content-ratings-using-html-calculated-columns/ of changing a calculated column to a numeric (to dynamically generate a link) doesn't seem to be working anymore...(which I need to get to a facility page).

So....instead of a classic page, I try and make the jump to the modern page (first time). I figure out a schema, and I've got my dynamic link back -- but I can't figure out how to create a similar dynamic search feature similar to what I had previously (using the HTML Form Web Part).

Has anyone had any success using OOTB features to filter information in a list? I don't have access to put a PowerApps on my page (which looks like it can do it)...so I'm hoping I can use SharePoint alone. It looks like with embed, we may be able to get it close?  https://support.microsoft.com/en-us/office/connect-web-parts-in-sharepoint-b457668c-d843-4b1b-8977-a6f9228a1dec?ui=en-us&rs=en-us&ad=us Also found a blog that talked about using "https://sharepoint.stackexchange.com/questions/270857/how-to-filter-list-items-and-documentsuseFiltersInViewXml=https://sharepoint.stackexchange.com/questions/270857/how-to-filter-list-items-and-documents".

I don't have an IT background, but any recommendations would be helpful.

Thank you!
