Google Colab is quite easy to use and has the benefit of not making your local computer feel sluggish while you run the training. The linked Unsloth post provides a notebook that can be launched there and I've had pretty good luck adapting their other notebooks with different foundational models. As a sibling noted, if you're using LORA instead of a full fine-tune, you can create adapters for fairly large models with the VRAM available in Colab, especially the paid plans.

If you have a Mac, you can also do pretty well training LORA adapters using something like Llama-Factory, and allowing it to run overnight. It's slower than an NVIDIA GPU but the increased effective memory size (if you say have 128GB) can allow you more flexibility.
