I've yet to see the latest, but as far as the official copy goes, it's a sequel and not a reboot.

Based on this, this is an "attempt to reboot the series". If this is correct, it shouldn't be part of this collection.

Are reboots and sequels mutually exclusive according to TMDb? One example that comes to mind is Mad Max: Fury Road, which this article considers to be a reboot, and which is considered part of the Mad Max Collection in TMDb.

That definitely isn't the use of the word "reboot" here as it refers to Chevy Chase, the star of the first two Fletch films, attempts to restart the series. If we're using Wiki as gospel, you need look no farther than the top of the page:

Confess, Fletch is a 2022 American crime comedy film directed by Greg Mottola, who also co-wrote the screenplay with Zev Borow. Based on Gregory Mcdonald's 1976 novel of the same name, the film stars Jon Hamm, Lorenza Izzo, Marcia Gay Harden, Kyle MacLachlan, Roy Wood Jr., and John Slattery. It is the third installment in the Fletch series, following Fletch (1985) and Fletch Lives (1989), and the first not to star Chevy Chase.

"Confess, Fletch" might be the third film in the Fletch film series but that doesn't mean it's related to the Chevy Chase films. Collections are for true movie sequels, and/or prequels in some cases, only.

From my understanding, "Confess, Fletch" is a new movie based on the same source material as the previous movies but unrelated to them (i.e. a reboot) so it shouldn't be added to this collection. If "Confess, Fletch" ends up having a sequel, a new collection should be created for them.

Having now seen the film itself, I can properly report that it is indeed a direct sequel to 'Fletch' (1985). It is based on the second book in the series and fully acknowledges the titular character's past daring-do as portrayed in the original film. Clearly, the filmmakers anticipate their audience's familiarity with Fleth's earlier incarnation and literally preclude a reboot by accepting the first film as canon. Chevy Chase is pushing 80, so recasting the central role was as inevitable after three decades, nor is it a very singular occurrence (and practically de rigueur among detective serials.) It is no less a sequel than the general preponderance of film series here and far from the most dubious entries among less storied franchises. I fail to see the applied interpretation made to date, which appears to be based on the colloquial use of a word by a random Wiki editor which doesn't even refer to this film. I humbly invite either of the attending mods to reconsider their position.

May I assure everyone, having personally reviewed every single "collection" on this site and failed in a few attempts to amend them, there is no actual unified standard governing their construction (several are quite a mess, while others have thankfully survived culling.) Equally, I must say, I generally find these terms invoked to a determent of proper understanding of the relationships between films. While I appreciate that the muddle of big-tent-filmapalooza wants for these kinds of narrow strictures, lest Matt Salinger's mug feature next to one of Hollywood's finer Chrisses, beyond those bounds, they fail to account for very genuine film series or reasonably divvy up some of the overpopulated ones along obvious faultlines. The galling removal of the formerly existent Éric Rohmer collections, in particular, only proves that any passion for film has been abandoned, one presumes, in favor of servicing nerd rage over the contaminating spirits of 'Ghostbusters' (2016) and other such ungermane preoccupations. The need for more thoughtful revision and general accommodation is very real.
