Recommended floor mats and cargo liners for the BMW i4?

So I finally took delivery of my i4 eDrive40 last week and Im already stressing about the interior. Ive been a BMW guy for a decade, had the F30 and a G20, and I usually just grab the OEM rubber mats from the dealer and call it a day but the ones they showed me for the i4 felt... thin? Like they arent the same quality as they used to be and the coverage seemed a bit skimpy. Plus with the specific floor layout on the EV I want to make sure I get the coverage right around the dead pedal and under the seats since my kids already tracked mud in today.

Im looking for a set that hits these points:

• Must be high-walled for heavy rain since Im up in Seattle and its basically a swamp 8 months a year
• Cargo liner needs to be grippy so my camera gear doesnt slide around the trunk every time I take a corner
• Needs to look sleek, not like a rugged off-road mat because it clashes with the interior trim
• Budget is around $300 for everything

Has anyone tried the TuxMat or 3D MAXpider in the i4 yet? I heard there might be fitment issues with the floor hump in the back compared to the gas 4 series. I need to get these ordered by next week before we head out on a road trip...
