Honestly, I think the biggest payback will be from page compressing the data (whether you use separate filegroups or not).
As always, it's vital to have the best clustered index on...

Yes. Use a CROSS APPLY or OUTER APPLY (rather than a JOIN) with a TOP (1) ORDER BY LEN(<matched_column>) DESC

Option 1 has performance issues.
Not necessarily.

Dynamically create a view that references all the applicable tables at the moment your code started running.
For example, roughly like this. [Edits in italics] You didn't give any real details...

To make it (much) less fragile, I would likely automate the creation of the Alerts by using a proc, via sp_add_alert.
The proc would take in the % size as a...

In SQL Server Agent; "Alerts"; "New Alert"; "SQL Server performance...
