Hi Josh,
Welcome to BPL. Lots of good info available on this site including some trip reports from around the central coast, mainly in and around Los Padres National Forest.
Given that you're new to this stuff, I've highlighted a couple of the more well known and well maintained trails for you to consider. There's 100s of miles of trails in the Los Padres but easy access and/or trail upkeep is often lacking, so these are a good place for you start.
Here's some ideas for you for possible trips…
In the Big Sur area, the most heavily used trail is the Pine Ridge Trail that leaves from the Big Sur Station just south of the big Julia Pfeiffer State Park campground. This trail will take you to Ventana, Barlow Flats, Sykes camps and beyond. It's well maintained, has lots of water and all of the camps are nestled amongst the redwoods. Barlow Flats might be a nice destination for you to base camp at and then dayhike up to check out Sykes on day 2. Sykes has hot springs but the area and the hot springs themselves have been overun with people. Ventana Camp used to be nice and has a great swimming hole; I haven't been there in years but I've heard the spur trail that takes you there from the Pine Ridge trail has been neglected since the fires. Not sure if this has changed or not. I believe fishing is allowed in the upper reaches of the Big Sur River but only from late May to October and only with barbless hooks; check with Fish and Game to confirm.
A little closer to you, are the trailheads at Salmon Creek Station (Buckeye Trail), and just north from there, the Cruicshank Trail to Villa Creek. Both of these are nice, easy trails with good views of the ocean and nice camp spots near creeks. Villa Creek camp is set amidst the southern-most stand of Coast Redwoods.
For any trail in Big Sur, watch out for PO and as we get into spring, ticks.
Down around Santa Barbara area, the trails in the San Rafael Wilderness accessed from NIRA camp behind Santa Ynez are nice and well maintained. You can follow the Manzana Creek Trail downstream to the Manzana Schoolhouse (about 9 miles each way; mostly flat) at the confluence of Manzana Creek and the Sisquoc River. You can also follow the Manzana Creek trail upstream to the Manzana Narrows and beyond. It's similar setting to the Sespe Creek Trail, but with more trees; not quite as desert-like. No fishing allowed here anymore.
Down closer to your last hike in the Sespe Wilderness, there's a couple of options to get into the Sespe high country and hike and camp amidst the Cedar forests along the Pine Mountain Ridge. You could access the area via Hwy 166 to Hwy 33 to Lockwood Valley Road and then head to the TH behind Camp Sheideck. There's some nice camps back there with reliable water set amidst the pines like Beartrap Camps and Haddock Camp. The trail continues all the way over the Pine Mountain Ridge and terminates at the Sespe River TH. The trail is generally in good shape too.
