Starting a new YT channel. Ideas?

I've created a new YouTube channel that I have yet to release. I've looked over my last channel countless times and I believe that I've fcked it up in terms of YouTube's algorithm. It's best that I drop it at this point. 5 years worth of cringy content gone. Bye.
So what would be some interesting content to start off with on this new channel? I want to stay as original as possibly yet not restrict my channel's content style too much. And of course I'll need to keep each video familiar/relatable enough for any current viewers to want to keep coming back. I haven't the slightest idea on what kind of content I'd like to produce since I'd enjoy trying to make just about anything. This is where I ask for other people's input. Your input.
But if there's an idea I could give for the start of it, I'd love to put in some satire on the fake fairyland vloggers for the first or second video. *Not so much be anti-'normie' but rather cast a light on the fake values and emotions that some YouTubers try to hammer into their community. I believe it's a way to relate and stick out? I don't know. Just an idea I'm looking to extend upon with the one or two people who may have an interest in such an odd topic for a Minecraft forum. I'm not 100% on what I'm doing which is why I'm back to square 1. My advise is likely as good as any of yours.

 

I'm not really planning on exposing channels in the edgy way you'd typically see across the platform. But I'd love to get into the realm of satire and essentially 'exposing' some channels that come off as fake and manipulative. I've talked with a friend about running the channel with me and we've come to an agreement that we won't restrict the channel's content type as long as it doesn't alienate our viewers. So ideas can pretty much ping-pong around the board without a barrier.
Some other ideas that have been tacked onto the content list:
-101 YouTube channel ideas list: This is where we'll make a series of videos exploring other YouTube channels for 'advise' which is where most of the satire and exposing will be done. We also plan to dilute the toxic outlook on YouTube by shedding some light on channels that seem to be doing things right.
-Lets Plays: Might as well add onto the abundance of lets plays on YouTube. We'll primarily do this when filming is slow and/or we're doing live streams.
-Builds/Makes: We're both Engineers so why not build something? We'll likely end up making useless and pointless things which will have entertainment value for sure.
-Channel Critiquing: I don't see this too often on a small scale and I just though of trying it out. We could ask viewers to email us their channel and/or videos they'd like for us to review and we'll do your typical 'reaction' style video as we analyse it/them. It could be helpful and the mini-series would have plenty of moments for goofs.

I'll keep adding to the physical list I have as ideas continue to dribble out.
And we'll continue having fun with producing videos since it's something we enjoy doing on our spare time. The biggest thing we'll have to work on is not being too fixated on content type or undermining the content type so much that it confuses subscribers. There's a balance point that we'll find as we test the waters out.
