What's your daily drive like? Distance? Weather? High speed freeway driving, or grid locked traffic? How many days per week?
A PHEV can be better for the environment than a full EV if we're taking a societal view rather than an individual one. If you're not doing a ton of miles each day, then a new PHEV would give you most or all of the EV benefits, with a much lower environmental impact from production.
For example, the Model Y you're considering has at least a 75kwh battery pack. If you drive 10k miles per year, then 100% of your miles driven would be done in EV mode. So you're using 75kwh of rare battery materials to replace 10k miles of ICE driving with EV driving. After 5 years, you've replaced 50k ICE miles with 50k EV miles. After 10 years, you've fully replaced 100k ICE miles with EV miles. This probably makes the owner feel good about their efforts. But what happens if we divided that 75kwh of battery materials among more than 1 vehicle?
A Rav 4 Prime (PHEV) has 42miles of EV range from an 18kwh battery pack. So with the same 50 mile drive, the PHEV does ~ 80% of it's miles as EV and 20% as ICE. So 8k EV miles per year and 2k ICE miles. After 5 years, you've replaced 40k ICE miles with EV miles.
That's not as good as fully replacing all of your individual 50k miles, but the much smaller battery capacity means the remaining raw materials can go towards other vehicles. The 75kwh of raw battery materials needed for the Model Y can be spread out among 4 Rav 4 Primes. So if each of them is also doing 80% of their miles as an EV, then each year there are 32k ICE miles replaced by ICE. At the 5 year mark, there are 160k ICe miles replaced by EV miles, and a decade later, the multiple PHEVs have replaced 320k ICE miles with EV miles using the same amount of raw battery materials as the single Model Y that only replaced 100k miles of ICE driving.
Obviously the math changes depending on the electric range of the specific PHEV you choose and of course the amount and type of driving that you do. But the larger point is that with current battery tech, battery materials are not easy to come by, and pretty harmful to obtain/turn into functional batteries. As a planet, our goal should be to replace as many ICE miles with EV miles as possible, while using as little raw material as possible. Full EVs with 250+ miles of range are actually somewhat counter productive to that goal because they hoard a bunch of harmful battery materials into a single battery pack that's rarely used to it's full capacity. Spreading out those raw materials among as many vehicles as we can (PHEVs) not only has larger environmental benefit, but it occurs faster and with less hesitation from consumers who (rightfully or not) have concerns about range/charging infrastructure/etc. It's understandable to want to replace your ICE with an EV so that 100% of the miles that you drive are converted into EV miles. But I'd argue that hauling around that unused battery capacity comes with a significant environmental cost as well, and that PHEVs can be considered the more environmentally conscious choice.
The PHEVs can also be significantly less expensive too. A Model Y currently starts at $65k and has no tax credit available. A Rav 4 Prime or Santa Fe PHEV start just over $40k with some amount of credit. A Pacifica Hybrid minivan would be way more practical/functional at moving people and things for $50k. That's not including smaller and cheaper PHEV options like the Ford Escape, Kia Niro, Hyundai Tuscon, etc.
