Europe has literally thousands of ski resorts. So I'll focus on the Alps. There I can recommend you two small ski resorts that are well suited for beginners. There are various reasons for this. Small ski resorts are generally cheaper. So you don't have to spend a lot of money for runs you won't ever use because they're too step. Additionally, small resorts are often less crowded. This seems contra-intuitive, but it is generally true, because all people aim to go for big resorts. And third, small ski resorts tend to have less uphill sections because they are not so widespread and that's why they don't have long connection passages.
In Austria I would recommend Laterns. There are both drag lifts and chair lifts, but you can easily avoid the drag lifts. As far as I remember there aren't any uphill sections at all. Just two small ones before restaurants. But you can avoid that as well if you want ;)
The second small ski resort I can recommend is Malbun in Liechtenstein. There is only 1 drag lift and 2 chair lifts. There are no uphill sections at all and the prices are relatively cheap compared to the neighboring countries. The runs are generally very wide and if you go there on a weekday in the morning you're literally alone there ;) Additionally one of the chair lift is very modern. You can pull down a cover if its very winding or you're freezing and the chairs are heated.
