Is it worth considering an increase in the block size limit again, or are there alternative solutions that the community is leaning toward?
I believe Bitcoin block size limit should be increased, with reasonable limit and testing. But majority of Bitcoin community prefer continue to develop LN, sidechain or other L2 solutions.

I highly doubt it. The best argument for 4 MB block size is that we already have 4 MB block size.
Or rather up to 4MB block size. In last year, block have average size 1.66MB[1] since only part of TX considered as witness data.
The roadmap since 2017 is focused on second layer solutions, as arbitrarily messing with the block size introduces a lot of problems, and it has already attempted and failed in the past. (Bitcoin Cash & SV)
That's true. Although it's worth to mention that BSV failed since it's created by fraud and scammer, while BCH riddled with many controversy (such as supported by Jihan Wu who implement covert ASICBoost[2] which isn't compatible with SegWit).
