Secure
The Foundation secures anomalies with the goal of preventing them from falling into the hands of civilian or rival agencies, through extensive observation and surveillance and by acting to intercept such anomalies at the earliest opportunity.
Contain
The Foundation contains anomalies with the goal of preventing their influence or effects from spreading, by either relocating, concealing, or dismantling such anomalies or by suppressing or preventing public dissemination of knowledge thereof.
Protect
The Foundation protects humanity from the effects of such anomalies as well as the anomalies themselves until such time that they are either fully understood or new theories of science can be devised based on their properties and behavior. The Foundation may also neutralize or destroy anomalies as an option of last resort, if they are determined to be too dangerous to be contained.
I usually recommend starting at the beginning and reading forward from there. At some point you may feel like bouncing around. It looks like they've broken up the entries into series since I was last there.
Ohhh
Anti-memes is my all-time favorite. https://scp-wiki.wikidot.com/antimemetics-division-hub
Its too bad no such SCP division exists.
It's incredible how good it is. It's up there as some of my favorite fiction ever.
I'd just go with the all time top rated list
I'd recommend against that, that list is just all the original ones, which aren't all to good, and don't give the right impression of the current state of the wiki.
I would recommend reading the wiki pages about the basic parts of the wiki(object classes, MTFs, the format, etc.) Then reading 1 or 2 series 1/2 scps, and then diving into more recent ones. If there's something you don't quite get, then you can probably find a page about it.

SCP-882 for an intro to the Church of the Broken God, with several other SCPs linked at the bottom that will draw you into the rabbit hole.
SCP-354 (The Red Pool) because it's just a classic, with a nice long log entry to read through.
SCP-140, the SCP that founded the Daevites as a faction. No crosslinks, but click on the 'daevite' tag at the bottom if you want to browse. Or take a gander at SCP-076 (Abel) if you want to be drawn into a whole other tangentially related rabbit hole, one dug by the Foundation's own hubris.
I enjoy listening to 'the exploring series' on YouTube.
Daybreak.
