Let's presume a kitchen with the appropriate number of small appliance branch circuits and receptacles. We have a toaster oven (1800W). It just sits on the countertop, not fastened in place in the common usage of that phrase. Does it therefore fall under 220.52(A) (Small Appliance), 220.53 (Appliance Load), or under 220.55 (Electric Cooking Appliances)?

Our area is still using the 2017 code. Here is the text for reference:

220.52(A)220.53220.55
Small-Appliance Circuit Load. In each dwelling unit, the load shall be calculated at 1500 volt-amperes for each 2-wire small-appliance branch circuit as covered by 210.11(C)(1).

Where the load is subdivided through two or more feeders, the calculated load for each shall include not less than 1500 voltamperes for each 2-wire small-appliance branch circuit. These loads shall be permitted to be included with the general lighting
load.
Appliance Load — Dwelling Unit(s). It shall be
permissible to apply a demand factor of 75 percent to the nameplate rating load of four or more appliances fastened in place, other than electric ranges, clothes dryers, space-heating equipment, or air-conditioning equipment, that are served by the same feeder or service in a one-family, two-family, or multifamily dwelling.
Electric Cooking Appliances in Dwelling Units and Household Cooking Appliances Used in Instructional Programs. The load for household electric ranges, wall-mounted ovens, counter-mounted cooking units, and other
household cooking appliances individually rated in excess of 1-3∕4 kW shall be permitted to be calculated in accordance with Table 220.55. Kilovolt-amperes (kVA) shall be considered equivalent to kilowatts (kW) for loads calculated under this section.

Where two or more single-phase ranges are supplied by a 3-phase, 4-wire feeder or service, the total load shall be calculated on the basis of twice the maximum number connected between any two phases.

If its a portable cord and plug connected toaster oven like you said 220.52(A).
NEC load calculations have plenty of extra factored in for that extra 300 watts.
