I mean the Xbox Series S will be a 4 year old non-high-end console by the time the Switch 2 will be released. I can definitely see them go in that direction.
Maybe it will have more RAM, but it will most likely have slower/cheaper RAM. LPDDR5 or LPDDR5X instead of GDDR6. Should also be more power efficient.
I bet the Switch 2's SoC will include a GPU based on Ampere or newer, which means RTX 3000 series capabilities which. Nvidia Tegra Orin from 2019 already included that much.
Of course it will be very likely more limited than even a 3060 mobile chip, but it could include both RT and DLSS 3.5 if they wanted to. I doubt they use RT but DLSS would make a lot of sense.
